Steps to Calculate GCD of 305, 663, 551, 631 using LCM Formula
Given numbers are 305, 663, 551, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 663) = 202215
GCD(305, 663) = ( 305 x 663 ) / 202215
= 305 / 663
= 305
Step2:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 305, 663, 551, 631 is 1
