Steps to Calculate GCD of 251, 305, 463, 681 using LCM Formula
Given numbers are 251, 305, 463, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 305) = 76555
GCD(251, 305) = ( 251 x 305 ) / 76555
= 251 / 305
= 251
Step2:
LCM(1, 463) = 463
GCD(1, 463) = ( 1 x 463 ) / 463
= 1 / 463
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 251, 305, 463, 681 is 1
