Given numbers are 980, 780, 826, 681

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 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 826 are 2 x 7 x 59

Prime factors of 681 are 3 x 227

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

Given numbers are 980, 780, 826, 681

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

Apply this formula for all numbers.

Step1:

LCM(980, 780) = 38220

GCD(980, 780) = ( 980 x 780 ) / 38220

= 980 / 780

= 980

Step2:

LCM(20, 826) = 8260

GCD(20, 826) = ( 20 x 826 ) / 8260

= 20 / 826

= 20

Step3:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

So, Greatest Common Divisor of 980, 780, 826, 681 is 1
