Answer 1

Answer:

Find the prime factorization of 36

Find the prime factorization of 42

42 = 2 × 3 × 7

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

LCM = 2 × 2 × 3 × 3 × 7

LCM = 252

Step-by-step explanation:

HCF of 36 and 42 by Long Division

Step 1: Divide 42 by 36 and check the remainder.

Step 2: Make the remainder 6 as the new divisor and the previous divisor 36 is the dividend and perform the long division again. The last divisor is our HCF.

Step 3: Continue till you get the remainder as 0.
