How to Find LCM of 48 and 64?

LCM of 48 and 64 can be determined using three methods:

  • Prime Factorisation
  • Division method
  • Listing the multiples

LCM of 48 and 64 Using Prime Factorisation Method

Here, the given natural numbers are expressed as the product of prime factors. Hence the numbers 48 and 64 are written as;

48 = 2 × 2 × 2 × 2 × 3

64 = 2 × 2 × 2 × 2 × 2 × 2

LCM (48, 64) = 2 × 2 × 2 × 2 × 2 × 2 × 3 = 192

LCM of 48 and 64 Using Division Method

In this method, to calculate the LCM, we divide the numbers 48 and 64 by their prime factors until we get the result as one in the complete row. The product of these divisors denotes the least common multiple of 48 and 64.

2 48 64
2 24 32
2 12 16
2 6 8
2 3 4
2 3 2
3 3 1
x 1 1

No more further division can be done.

Hence, LCM (48, 64) = 2 × 2 × 2 × 2 × 2 × 2 × 3 = 192
