Steps to Calculate GCD of 392, 872, 392, 861 using LCM Formula
Given numbers are 392, 872, 392, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 872) = 42728
GCD(392, 872) = ( 392 x 872 ) / 42728
= 392 / 872
= 392
Step2:
LCM(8, 392) = 392
GCD(8, 392) = ( 8 x 392 ) / 392
= 8 / 392
= 8
Step3:
LCM(8, 861) = 6888
GCD(8, 861) = ( 8 x 861 ) / 6888
= 8 / 861
= 8
So, Greatest Common Divisor of 392, 872, 392, 861 is 1
