Steps to Calculate GCD of 830, 141, 979, 638 using LCM Formula
Given numbers are 830, 141, 979, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 141) = 117030
GCD(830, 141) = ( 830 x 141 ) / 117030
= 830 / 141
= 830
Step2:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 830, 141, 979, 638 is 1
