Steps to Calculate GCD of 687, 813, 847, 845 using LCM Formula
Given numbers are 687, 813, 847, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 813) = 186177
GCD(687, 813) = ( 687 x 813 ) / 186177
= 687 / 813
= 687
Step2:
LCM(3, 847) = 2541
GCD(3, 847) = ( 3 x 847 ) / 2541
= 3 / 847
= 3
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 687, 813, 847, 845 is 1
