Steps to Calculate GCD of 278, 455, 197, 455 using LCM Formula
Given numbers are 278, 455, 197, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 455) = 126490
GCD(278, 455) = ( 278 x 455 ) / 126490
= 278 / 455
= 278
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 278, 455, 197, 455 is 1
