Steps to Calculate GCD of 395, 447, 142, 154 using LCM Formula
Given numbers are 395, 447, 142, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 447) = 176565
GCD(395, 447) = ( 395 x 447 ) / 176565
= 395 / 447
= 395
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 395, 447, 142, 154 is 1
