Given numbers are 220, 851, 641, 691

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 851 are 23 x 37

Prime factors of 641 are 641

Prime factors of 691 are 691

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

Given numbers are 220, 851, 641, 691

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

Apply this formula for all numbers.

Step1:

LCM(220, 851) = 187220

GCD(220, 851) = ( 220 x 851 ) / 187220

= 220 / 851

= 220

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 220, 851, 641, 691 is 1
