Given numbers are 561, 459, 758, 653

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

Apply this formula for all numbers.

Step1:

LCM(561, 459) = 5049

GCD(561, 459) = ( 561 x 459 ) / 5049

= 561 / 459

= 561

Step2:

LCM(51, 758) = 38658

GCD(51, 758) = ( 51 x 758 ) / 38658

= 51 / 758

= 51

Step3:

LCM(1, 653) = 653

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

= 1 / 653

= 1

So, Greatest Common Divisor of 561, 459, 758, 653 is 1
