Given numbers are 657, 212, 679

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

Apply this formula for all numbers.

Step1:

LCM(657, 212) = 139284

GCD(657, 212) = ( 657 x 212 ) / 139284

= 657 / 212

= 657

Step2:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

So, Greatest Common Divisor of 657, 212, 679 is 1
