Given numbers are 84, 82, 77

The list of prime factors of all numbers are

Prime factors of 84 are 2 x 2 x 3 x 7

Prime factors of 82 are 2 x 41

Prime factors of 77 are 7 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 84, 82, 77

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(84, 82) = 3444

GCD(84, 82) = ( 84 x 82 ) / 3444

= 84 / 82

= 84

Step2:

LCM(2, 77) = 154

GCD(2, 77) = ( 2 x 77 ) / 154

= 2 / 77

= 2

So, Greatest Common Divisor of 84, 82, 77 is 1
