Steps to Calculate GCD of 139, 390, 249, 613 using LCM Formula
Given numbers are 139, 390, 249, 613
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 390) = 54210
GCD(139, 390) = ( 139 x 390 ) / 54210
= 139 / 390
= 139
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
So, Greatest Common Divisor of 139, 390, 249, 613 is 1
