Steps to Calculate GCD of 649, 122, 197, 145 using LCM Formula
Given numbers are 649, 122, 197, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 122) = 79178
GCD(649, 122) = ( 649 x 122 ) / 79178
= 649 / 122
= 649
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 649, 122, 197, 145 is 1
