Steps to Calculate GCD of 842, 638, 644, 105 using LCM Formula
Given numbers are 842, 638, 644, 105
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 638) = 268598
GCD(842, 638) = ( 842 x 638 ) / 268598
= 842 / 638
= 842
Step2:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
Step3:
LCM(2, 105) = 210
GCD(2, 105) = ( 2 x 105 ) / 210
= 2 / 105
= 2
So, Greatest Common Divisor of 842, 638, 644, 105 is 1
