Given numbers are 656, 412, 451, 618

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

Apply this formula for all numbers.

Step1:

LCM(656, 412) = 67568

GCD(656, 412) = ( 656 x 412 ) / 67568

= 656 / 412

= 656

Step2:

LCM(4, 451) = 1804

GCD(4, 451) = ( 4 x 451 ) / 1804

= 4 / 451

= 4

Step3:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 656, 412, 451, 618 is 1
