Given numbers are 420, 536, 957, 691

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 536 are 2 x 2 x 2 x 67

Prime factors of 957 are 3 x 11 x 29

Prime factors of 691 are 691

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

Given numbers are 420, 536, 957, 691

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

Apply this formula for all numbers.

Step1:

LCM(420, 536) = 56280

GCD(420, 536) = ( 420 x 536 ) / 56280

= 420 / 536

= 420

Step2:

LCM(4, 957) = 3828

GCD(4, 957) = ( 4 x 957 ) / 3828

= 4 / 957

= 4

Step3:

LCM(1, 691) = 691

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

= 1 / 691

= 1

So, Greatest Common Divisor of 420, 536, 957, 691 is 1
