Steps to Calculate GCD of 251, 222, 61, 774 using LCM Formula
Given numbers are 251, 222, 61, 774
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 222) = 55722
GCD(251, 222) = ( 251 x 222 ) / 55722
= 251 / 222
= 251
Step2:
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
= 1 / 61
= 1
Step3:
LCM(1, 774) = 774
GCD(1, 774) = ( 1 x 774 ) / 774
= 1 / 774
= 1
So, Greatest Common Divisor of 251, 222, 61, 774 is 1
