Question

longest division method of 42,72 hcg​

Answer 1

Answer:

6

Step-by-step explanation:

Even though the question says HCG, I'm assuming it's just a typo and you'd like the HCF of 42 and 72 using long division method.

For that, we first divide the smaller number by the bigger.

72/42 leaves 30 as remainder.

We take this remainder and then divide 42 using 30.

42/30 leaves us with a reminder of 12.

We'll repeat the process until the remainder is zero. The divisor in that case will be the HCF.

30/12 leaves a remainder of 6.

12/6 leaves no remainder. Thus, the HCF of 42 & 72 is 6.
