Steps to Calculate GCD of 405, 627, 647, 283 using LCM Formula
Given numbers are 405, 627, 647, 283
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 627) = 84645
GCD(405, 627) = ( 405 x 627 ) / 84645
= 405 / 627
= 405
Step2:
LCM(3, 647) = 1941
GCD(3, 647) = ( 3 x 647 ) / 1941
= 3 / 647
= 3
Step3:
LCM(1, 283) = 283
GCD(1, 283) = ( 1 x 283 ) / 283
= 1 / 283
= 1
So, Greatest Common Divisor of 405, 627, 647, 283 is 1
