Steps to Calculate GCD of 812, 542, 38, 989 using LCM Formula
Given numbers are 812, 542, 38, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 542) = 220052
GCD(812, 542) = ( 812 x 542 ) / 220052
= 812 / 542
= 812
Step2:
LCM(2, 38) = 38
GCD(2, 38) = ( 2 x 38 ) / 38
= 2 / 38
= 2
Step3:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
So, Greatest Common Divisor of 812, 542, 38, 989 is 1
