Steps to Calculate GCD of 427, 588, 18, 649 using LCM Formula
Given numbers are 427, 588, 18, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 588) = 35868
GCD(427, 588) = ( 427 x 588 ) / 35868
= 427 / 588
= 427
Step2:
LCM(7, 18) = 126
GCD(7, 18) = ( 7 x 18 ) / 126
= 7 / 18
= 7
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 427, 588, 18, 649 is 1
