Steps to Calculate GCD of 981, 183, 39, 790 using LCM Formula
Given numbers are 981, 183, 39, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 183) = 59841
GCD(981, 183) = ( 981 x 183 ) / 59841
= 981 / 183
= 981
Step2:
LCM(3, 39) = 39
GCD(3, 39) = ( 3 x 39 ) / 39
= 3 / 39
= 3
Step3:
LCM(3, 790) = 2370
GCD(3, 790) = ( 3 x 790 ) / 2370
= 3 / 790
= 3
So, Greatest Common Divisor of 981, 183, 39, 790 is 1
