Given numbers are 257, 771, 678, 956

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

Apply this formula for all numbers.

Step1:

LCM(257, 771) = 771

GCD(257, 771) = ( 257 x 771 ) / 771

= 257 / 771

= 257

Step2:

LCM(257, 678) = 174246

GCD(257, 678) = ( 257 x 678 ) / 174246

= 257 / 678

= 257

Step3:

LCM(1, 956) = 956

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

= 1 / 956

= 1

So, Greatest Common Divisor of 257, 771, 678, 956 is 1
