GCD of numbers is the greatest common divisor

So, the GCD (980, 660, 780, 517) = 1.

Given numbers are 980, 660, 780, 517

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 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 517 are 11 x 47

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

Given numbers are 980, 660, 780, 517

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

Apply this formula for all numbers.

Step1:

LCM(980, 660) = 32340

GCD(980, 660) = ( 980 x 660 ) / 32340

= 980 / 660

= 980

Step2:

LCM(20, 780) = 780

GCD(20, 780) = ( 20 x 780 ) / 780

= 20 / 780

= 20

Step3:

LCM(20, 517) = 10340

GCD(20, 517) = ( 20 x 517 ) / 10340

= 20 / 517

= 20

So, Greatest Common Divisor of 980, 660, 780, 517 is 1
