Answer:
1. Find the HCF of 42,70 and 112
answer is:- HCF (42, 70, 112) = 14
Step-by-step explanation:
Euclid's Division. Lemma: a = bq + r where 0 ≤ r ≤ b is the Highest common factor (HCF) of 42, 70, 112 and we need to find the HCF of these numbers. To do so, we first need to choose the largest integer first and then identify the highest common factor of those two numbers.
Other example Find the HCF of 36, 24 and 12
Ans Written each number as a product of its prime factors.
22 x 32 = 36
23 x 3 = 24
22 x 3 = 12
The product of all common prime factors is the HCF (use the lowest power of each common factor) In this example, 2 & 3 are used to work out the product of two prime factors. The lowest power of 2 is 22 and 3 is 3.
So, HCF = 22 x 3 = 12
