Steps to Calculate GCD of 721, 287, 451, 887 using LCM Formula
Given numbers are 721, 287, 451, 887
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 287) = 29561
GCD(721, 287) = ( 721 x 287 ) / 29561
= 721 / 287
= 721
Step2:
LCM(7, 451) = 3157
GCD(7, 451) = ( 7 x 451 ) / 3157
= 7 / 451
= 7
Step3:
LCM(1, 887) = 887
GCD(1, 887) = ( 1 x 887 ) / 887
= 1 / 887
= 1
So, Greatest Common Divisor of 721, 287, 451, 887 is 1
