Steps to Calculate GCD of 822, 242, 638, 131 using LCM Formula
Given numbers are 822, 242, 638, 131
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 242) = 99462
GCD(822, 242) = ( 822 x 242 ) / 99462
= 822 / 242
= 822
Step2:
LCM(2, 638) = 638
GCD(2, 638) = ( 2 x 638 ) / 638
= 2 / 638
= 2
Step3:
LCM(2, 131) = 262
GCD(2, 131) = ( 2 x 131 ) / 262
= 2 / 131
= 2
So, Greatest Common Divisor of 822, 242, 638, 131 is 1
