Given numbers are 980, 820, 634, 634

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

Apply this formula for all numbers.

Step1:

LCM(980, 820) = 40180

GCD(980, 820) = ( 980 x 820 ) / 40180

= 980 / 820

= 980

Step2:

LCM(20, 634) = 6340

GCD(20, 634) = ( 20 x 634 ) / 6340

= 20 / 634

= 20

Step3:

LCM(2, 634) = 634

GCD(2, 634) = ( 2 x 634 ) / 634

= 2 / 634

= 2

So, Greatest Common Divisor of 980, 820, 634, 634 is 2
