Given numbers are 661, 310, 637, 956

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

Apply this formula for all numbers.

Step1:

LCM(661, 310) = 204910

GCD(661, 310) = ( 661 x 310 ) / 204910

= 661 / 310

= 661

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

So, Greatest Common Divisor of 661, 310, 637, 956 is 1
