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

Apply this formula for all numbers.

Step1:

LCM(921, 129) = 39603

GCD(921, 129) = ( 921 x 129 ) / 39603

= 921 / 129

= 921

Step2:

LCM(3, 525) = 525

GCD(3, 525) = ( 3 x 525 ) / 525

= 3 / 525

= 3

So, Greatest Common Divisor of 921, 129, 525 is 3
