Steps to Calculate GCD of 779, 871, 439, 257 using LCM Formula
Given numbers are 779, 871, 439, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(779, 871) = 678509
GCD(779, 871) = ( 779 x 871 ) / 678509
= 779 / 871
= 779
Step2:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 779, 871, 439, 257 is 1
