Given numbers are 522, 252, 651, 645

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

Apply this formula for all numbers.

Step1:

LCM(522, 252) = 7308

GCD(522, 252) = ( 522 x 252 ) / 7308

= 522 / 252

= 522

Step2:

LCM(18, 651) = 3906

GCD(18, 651) = ( 18 x 651 ) / 3906

= 18 / 651

= 18

Step3:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

So, Greatest Common Divisor of 522, 252, 651, 645 is 3
