Steps to Calculate GCD of 642, 246, 447, 218 using LCM Formula
Given numbers are 642, 246, 447, 218
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 246) = 26322
GCD(642, 246) = ( 642 x 246 ) / 26322
= 642 / 246
= 642
Step2:
LCM(6, 447) = 894
GCD(6, 447) = ( 6 x 447 ) / 894
= 6 / 447
= 6
Step3:
LCM(3, 218) = 654
GCD(3, 218) = ( 3 x 218 ) / 654
= 3 / 218
= 3
So, Greatest Common Divisor of 642, 246, 447, 218 is 1
