Given numbers are 657, 615, 639, 958

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

Apply this formula for all numbers.

Step1:

LCM(657, 615) = 134685

GCD(657, 615) = ( 657 x 615 ) / 134685

= 657 / 615

= 657

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 958) = 2874

GCD(3, 958) = ( 3 x 958 ) / 2874

= 3 / 958

= 3

So, Greatest Common Divisor of 657, 615, 639, 958 is 1
