Steps to Calculate GCD of 639, 267, 133, 551 using LCM Formula
Given numbers are 639, 267, 133, 551
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 267) = 56871
GCD(639, 267) = ( 639 x 267 ) / 56871
= 639 / 267
= 639
Step2:
LCM(3, 133) = 399
GCD(3, 133) = ( 3 x 133 ) / 399
= 3 / 133
= 3
Step3:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
So, Greatest Common Divisor of 639, 267, 133, 551 is 1
