The list of prime factors of all numbers are

Prime factors of 979 are 11 x 89

Prime factors of 142 are 2 x 71

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

Prime factors of 253 are 11 x 23

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

Given numbers are 979, 142, 220, 253

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

Apply this formula for all numbers.

Step1:

LCM(979, 142) = 139018

GCD(979, 142) = ( 979 x 142 ) / 139018

= 979 / 142

= 979

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 979, 142, 220, 253 is 1
