Given numbers are 963, 561, 988, 653

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

Apply this formula for all numbers.

Step1:

LCM(963, 561) = 180081

GCD(963, 561) = ( 963 x 561 ) / 180081

= 963 / 561

= 963

Step2:

LCM(3, 988) = 2964

GCD(3, 988) = ( 3 x 988 ) / 2964

= 3 / 988

= 3

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 963, 561, 988, 653 is 1
