Steps to Calculate GCD of 156, 349, 105, 407 using LCM Formula
Given numbers are 156, 349, 105, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 349) = 54444
GCD(156, 349) = ( 156 x 349 ) / 54444
= 156 / 349
= 156
Step2:
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
= 1 / 105
= 1
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 156, 349, 105, 407 is 1
