Given numbers are 657, 666, 631, 609

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

Apply this formula for all numbers.

Step1:

LCM(657, 666) = 48618

GCD(657, 666) = ( 657 x 666 ) / 48618

= 657 / 666

= 657

Step2:

LCM(9, 631) = 5679

GCD(9, 631) = ( 9 x 631 ) / 5679

= 9 / 631

= 9

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 657, 666, 631, 609 is 1
