Given numbers are 731, 951, 721, 980

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 951 are 3 x 317

Prime factors of 721 are 7 x 103

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

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

Given numbers are 731, 951, 721, 980

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

Apply this formula for all numbers.

Step1:

LCM(731, 951) = 695181

GCD(731, 951) = ( 731 x 951 ) / 695181

= 731 / 951

= 731

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 731, 951, 721, 980 is 1
