Steps to Calculate GCD of 635, 257, 155, 458 using LCM Formula
Given numbers are 635, 257, 155, 458
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(635, 257) = 163195
GCD(635, 257) = ( 635 x 257 ) / 163195
= 635 / 257
= 635
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
So, Greatest Common Divisor of 635, 257, 155, 458 is 1
