Steps to Calculate GCD of 387, 645, 73, 369 using LCM Formula
Given numbers are 387, 645, 73, 369
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 645) = 1935
GCD(387, 645) = ( 387 x 645 ) / 1935
= 387 / 645
= 387
Step2:
LCM(129, 73) = 9417
GCD(129, 73) = ( 129 x 73 ) / 9417
= 129 / 73
= 129
Step3:
LCM(1, 369) = 369
GCD(1, 369) = ( 1 x 369 ) / 369
= 1 / 369
= 1
So, Greatest Common Divisor of 387, 645, 73, 369 is 1
