Steps to Calculate GCD of 221, 298, 28, 231 using LCM Formula
Given numbers are 221, 298, 28, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 298) = 65858
GCD(221, 298) = ( 221 x 298 ) / 65858
= 221 / 298
= 221
Step2:
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
= 1 / 28
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 221, 298, 28, 231 is 1
