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

Given numbers are 980, 646, 798, 829

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

Apply this formula for all numbers.

Step1:

LCM(980, 646) = 316540

GCD(980, 646) = ( 980 x 646 ) / 316540

= 980 / 646

= 980

Step2:

LCM(2, 798) = 798

GCD(2, 798) = ( 2 x 798 ) / 798

= 2 / 798

= 2

Step3:

LCM(2, 829) = 1658

GCD(2, 829) = ( 2 x 829 ) / 1658

= 2 / 829

= 2

So, Greatest Common Divisor of 980, 646, 798, 829 is 1
