Steps to Calculate GCD of 872, 157, 319, 820 using LCM Formula
Given numbers are 872, 157, 319, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(872, 157) = 136904
GCD(872, 157) = ( 872 x 157 ) / 136904
= 872 / 157
= 872
Step2:
LCM(1, 319) = 319
GCD(1, 319) = ( 1 x 319 ) / 319
= 1 / 319
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 872, 157, 319, 820 is 1
