Steps to Calculate GCD of 915, 957, 13, 843 using LCM Formula
Given numbers are 915, 957, 13, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 957) = 291885
GCD(915, 957) = ( 915 x 957 ) / 291885
= 915 / 957
= 915
Step2:
LCM(3, 13) = 39
GCD(3, 13) = ( 3 x 13 ) / 39
= 3 / 13
= 3
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 915, 957, 13, 843 is 1
