Given numbers are 963, 732, 21, 517

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

Apply this formula for all numbers.

Step1:

LCM(963, 732) = 234972

GCD(963, 732) = ( 963 x 732 ) / 234972

= 963 / 732

= 963

Step2:

LCM(3, 21) = 21

GCD(3, 21) = ( 3 x 21 ) / 21

= 3 / 21

= 3

Step3:

LCM(3, 517) = 1551

GCD(3, 517) = ( 3 x 517 ) / 1551

= 3 / 517

= 3

So, Greatest Common Divisor of 963, 732, 21, 517 is 1
