Given numbers are 690, 980, 660, 634

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

Apply this formula for all numbers.

Step1:

LCM(690, 980) = 67620

GCD(690, 980) = ( 690 x 980 ) / 67620

= 690 / 980

= 690

Step2:

LCM(10, 660) = 660

GCD(10, 660) = ( 10 x 660 ) / 660

= 10 / 660

= 10

Step3:

LCM(10, 634) = 3170

GCD(10, 634) = ( 10 x 634 ) / 3170

= 10 / 634

= 10

So, Greatest Common Divisor of 690, 980, 660, 634 is 2
