Steps to Calculate GCD of 143, 197, 254, 421 using LCM Formula
Given numbers are 143, 197, 254, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(143, 197) = 28171
GCD(143, 197) = ( 143 x 197 ) / 28171
= 143 / 197
= 143
Step2:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 143, 197, 254, 421 is 1
