Steps to Calculate GCD of 287, 809, 647, 731 using LCM Formula
Given numbers are 287, 809, 647, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 809) = 232183
GCD(287, 809) = ( 287 x 809 ) / 232183
= 287 / 809
= 287
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 287, 809, 647, 731 is 1
