Given numbers are 771, 956, 639, 557

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

Apply this formula for all numbers.

Step1:

LCM(771, 956) = 737076

GCD(771, 956) = ( 771 x 956 ) / 737076

= 771 / 956

= 771

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 771, 956, 639, 557 is 1
