Steps to Calculate GCD of 149, 413, 405, 637 using LCM Formula
Given numbers are 149, 413, 405, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(149, 413) = 61537
GCD(149, 413) = ( 149 x 413 ) / 61537
= 149 / 413
= 149
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 149, 413, 405, 637 is 1
