Question

Find the HCF of 84, 88 by Common Division method

Answer 1

Answer:

Greatest common factor (GCF) of 84 and 88 is 4.

GCF(84,88) = 4

Step-by-step explanation:

We will now calculate the prime factors of 84 and 88, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 84 and 88.

Answer 2

$\bold \red{Answer}$

Bring down any numbers that are not evenly divisible by the prime number.

When the last row of results is all 1's you are done.

Find the product of the prime numbers in the first column to get the LCM:

LCM = 2 x 2 x 2 x 3 x 7 x 11

LCM = 1848

Therefore,

LCM(84, 88) = 1848
