Steps to Calculate GCD of 155, 931, 142, 603 using LCM Formula
Given numbers are 155, 931, 142, 603
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 931) = 144305
GCD(155, 931) = ( 155 x 931 ) / 144305
= 155 / 931
= 155
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 155, 931, 142, 603 is 1
