Steps to Calculate GCD of 915, 789, 814, 393 using LCM Formula
Given numbers are 915, 789, 814, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 789) = 240645
GCD(915, 789) = ( 915 x 789 ) / 240645
= 915 / 789
= 915
Step2:
LCM(3, 814) = 2442
GCD(3, 814) = ( 3 x 814 ) / 2442
= 3 / 814
= 3
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 915, 789, 814, 393 is 1
