Steps to Calculate GCD of 980, 420, 159 using LCM Formula
Given numbers are 980, 420, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 420) = 2940
GCD(980, 420) = ( 980 x 420 ) / 2940
= 980 / 420
= 980
Step2:
LCM(140, 159) = 22260
GCD(140, 159) = ( 140 x 159 ) / 22260
= 140 / 159
= 140
So, Greatest Common Divisor of 980, 420, 159 is 1
