Given numbers are 980, 965, 668, 560

The list of prime factors of all numbers are

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

Prime factors of 965 are 5 x 193

Prime factors of 668 are 2 x 2 x 167

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Given numbers are 980, 965, 668, 560

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

Apply this formula for all numbers.

Step1:

LCM(980, 965) = 189140

GCD(980, 965) = ( 980 x 965 ) / 189140

= 980 / 965

= 980

Step2:

LCM(5, 668) = 3340

GCD(5, 668) = ( 5 x 668 ) / 3340

= 5 / 668

= 5

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 980, 965, 668, 560 is 1
