Steps to Calculate GCD of 878, 511, 20, 715 using LCM Formula
Given numbers are 878, 511, 20, 715
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(878, 511) = 448658
GCD(878, 511) = ( 878 x 511 ) / 448658
= 878 / 511
= 878
Step2:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 878, 511, 20, 715 is 1
