Steps to Calculate GCD of 338, 787, 646, 115 using LCM Formula
Given numbers are 338, 787, 646, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(338, 787) = 266006
GCD(338, 787) = ( 338 x 787 ) / 266006
= 338 / 787
= 338
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 338, 787, 646, 115 is 1
