Steps to Calculate GCD of 287, 164, 63, 278 using LCM Formula
Given numbers are 287, 164, 63, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 164) = 1148
GCD(287, 164) = ( 287 x 164 ) / 1148
= 287 / 164
= 287
Step2:
LCM(41, 63) = 2583
GCD(41, 63) = ( 41 x 63 ) / 2583
= 41 / 63
= 41
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 287, 164, 63, 278 is 1
