Given numbers are 957, 163, 170, 840

The list of prime factors of all numbers are

Prime factors of 957 are 3 x 11 x 29

Prime factors of 163 are 163

Prime factors of 170 are 2 x 5 x 17

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 957, 163, 170, 840

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

Apply this formula for all numbers.

Step1:

LCM(957, 163) = 155991

GCD(957, 163) = ( 957 x 163 ) / 155991

= 957 / 163

= 957

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 957, 163, 170, 840 is 1
