Steps to Calculate GCD of 426, 521, 197, 989 using LCM Formula
Given numbers are 426, 521, 197, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(426, 521) = 221946
GCD(426, 521) = ( 426 x 521 ) / 221946
= 426 / 521
= 426
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 426, 521, 197, 989 is 1
