Given numbers are 981, 460, 628, 220

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 628 are 2 x 2 x 157

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

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

Given numbers are 981, 460, 628, 220

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

Apply this formula for all numbers.

Step1:

LCM(981, 460) = 451260

GCD(981, 460) = ( 981 x 460 ) / 451260

= 981 / 460

= 981

Step2:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

Step3:

LCM(1, 220) = 220

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

= 1 / 220

= 1

So, Greatest Common Divisor of 981, 460, 628, 220 is 1
