LCM of 4 and 6

Clarification:

The LCM of two non-zero integers, x(4) and y(6), is the smallest optimistic integer m(12) that’s divisible by each x(4) and y(6) with none the rest.

The strategies to search out the LCM of 4 and 6 are defined under.

  • By Itemizing Multiples
  • By Prime Factorization Technique
  • By Division Technique

LCM of 4 and 6 by Itemizing Multiples

LCM of 4 and 6 by Listing Multiples Method

To calculate the LCM of 4 and 6 by itemizing out the frequent multiples, we are able to comply with the given under steps:

  • Step 1: Listing a couple of multiples of 4 (4, 8, 12, 16, 20, 24, . . . . ) and 6 (6, 12, 18, 24, . . . . . )
  • Step 2: The frequent multiples from the multiples of 4 and 6 are 12, 24, . . .
  • Step 3: The frequent a number of of 4 and 6 is the smallest 12.

∴ The least frequent a number of of 4 and 6 = 12.

LCM of 4 and 6 by Prime Factorization

Prime factorization of 4 and 6 is (2 × 2) = 22 and (2 × 3) = 21 × 31 respectively. The LCM of 4 and 6 could be obtained by multiplying prime elements raised to their respective highest energy, ie 22 × 31 = 12. Therefore, the LCM of 4 and 6 by prime factorization is 12.

LCM of 4 and 6 by Division Technique

LCM of 4 and 6 by Division Method

To calculate the LCM of 4 and 6 by the division technique, we’ll divide the numbers(4, 6) by their prime elements (ideally frequent). The product of those divisors provides the LCM of 4 and 6.

  • Step 1: Discover the prime quantity that could be a issue of the smallest at the least one of many numbers, 4 and 6. Write this prime quantity(2) on the left of the given numbers(4 and 6), separated as per the ladder association.
  • Step 2: If any of the given numbers (4, 6) is a a number of of two, divide it by 2 and write the quotient under it. Carry down any quantity that’s not invisible by the prime quantity.
  • Step 3: Proceed the steps till solely 1s are left within the final row.

The LCM of 4 and 6 is the product of all prime numbers on the left, ie LCM(4, 6) by division technique = 2 × 2 × 3 = 12.

☛ Additionally Verify:

  • LCM of 8, 15 and 21 – 840
  • LCM of 8 and 14 – 56
  • LCM of 8, 10 and 15 – 120
  • LCM of two, 3 and 4 – 12
  • LCM of 42 and 70 – 210
