Given numbers are 763, 280, 980, 422

The list of prime factors of all numbers are

Prime factors of 763 are 7 x 109

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 422 are 2 x 211

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

Given numbers are 763, 280, 980, 422

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

Apply this formula for all numbers.

Step1:

LCM(763, 280) = 30520

GCD(763, 280) = ( 763 x 280 ) / 30520

= 763 / 280

= 763

Step2:

LCM(7, 980) = 980

GCD(7, 980) = ( 7 x 980 ) / 980

= 7 / 980

= 7

Step3:

LCM(7, 422) = 2954

GCD(7, 422) = ( 7 x 422 ) / 2954

= 7 / 422

= 7

So, Greatest Common Divisor of 763, 280, 980, 422 is 1
