Steps to Calculate GCD of 290, 105, 39, 191 using LCM Formula
Given numbers are 290, 105, 39, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 105) = 6090
GCD(290, 105) = ( 290 x 105 ) / 6090
= 290 / 105
= 290
Step2:
LCM(5, 39) = 195
GCD(5, 39) = ( 5 x 39 ) / 195
= 5 / 39
= 5
Step3:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
So, Greatest Common Divisor of 290, 105, 39, 191 is 1
