Given numbers are 858, 132, 977, 668

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 977 are 977

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 858, 132, 977, 668

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

Apply this formula for all numbers.

Step1:

LCM(858, 132) = 1716

GCD(858, 132) = ( 858 x 132 ) / 1716

= 858 / 132

= 858

Step2:

LCM(66, 977) = 64482

GCD(66, 977) = ( 66 x 977 ) / 64482

= 66 / 977

= 66

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 858, 132, 977, 668 is 1
