Steps to Calculate GCD of 251, 811, 170, 197 using LCM Formula
Given numbers are 251, 811, 170, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 811) = 203561
GCD(251, 811) = ( 251 x 811 ) / 203561
= 251 / 811
= 251
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 251, 811, 170, 197 is 1
