Steps to Calculate GCD of 251, 817, 509, 771 using LCM Formula
Given numbers are 251, 817, 509, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 817) = 205067
GCD(251, 817) = ( 251 x 817 ) / 205067
= 251 / 817
= 251
Step2:
LCM(1, 509) = 509
GCD(1, 509) = ( 1 x 509 ) / 509
= 1 / 509
= 1
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 251, 817, 509, 771 is 1
