Steps to Calculate GCD of 862, 353, 649, 400 using LCM Formula
Given numbers are 862, 353, 649, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 353) = 304286
GCD(862, 353) = ( 862 x 353 ) / 304286
= 862 / 353
= 862
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 400) = 400
GCD(1, 400) = ( 1 x 400 ) / 400
= 1 / 400
= 1
So, Greatest Common Divisor of 862, 353, 649, 400 is 1
