Steps to Calculate GCD of 257, 250, 668, 394 using LCM Formula
Given numbers are 257, 250, 668, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 250) = 64250
GCD(257, 250) = ( 257 x 250 ) / 64250
= 257 / 250
= 257
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 257, 250, 668, 394 is 1
