Steps to Calculate GCD of 254, 691, 665, 356 using LCM Formula
Given numbers are 254, 691, 665, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(254, 691) = 175514
GCD(254, 691) = ( 254 x 691 ) / 175514
= 254 / 691
= 254
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 254, 691, 665, 356 is 1
