Steps to Calculate GCD of 647, 189, 515, 403 using LCM Formula
Given numbers are 647, 189, 515, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 189) = 122283
GCD(647, 189) = ( 647 x 189 ) / 122283
= 647 / 189
= 647
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
So, Greatest Common Divisor of 647, 189, 515, 403 is 1
