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

Apply this formula for all numbers.

Step1:

LCM(987, 553) = 77973

GCD(987, 553) = ( 987 x 553 ) / 77973

= 987 / 553

= 987

Step2:

LCM(7, 126) = 126

GCD(7, 126) = ( 7 x 126 ) / 126

= 7 / 126

= 7

So, Greatest Common Divisor of 987, 553, 126 is 7
