Steps to Calculate GCD of 698, 120, 55, 139 using LCM Formula
Given numbers are 698, 120, 55, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(698, 120) = 41880
GCD(698, 120) = ( 698 x 120 ) / 41880
= 698 / 120
= 698
Step2:
LCM(2, 55) = 110
GCD(2, 55) = ( 2 x 55 ) / 110
= 2 / 55
= 2
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 698, 120, 55, 139 is 1
