Answer 1

Answer:

I HOPE ITS CORRECT ANSWER AND HELPFUL

Step-by-step explanation:

Steps to find LCM

Find the prime factorization of 64

64 = 2 × 2 × 2 × 2 × 2 × 2

Find the prime factorization of 78

78 = 2 × 3 × 13

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 13

LCM = 2496

or

lcm (64,78) = \frac{64 \times 78}{gcf(64,78)} = \frac{4992}{2}

gcf(64,78)64×78 = 2/4992 = 2496
