Steps to Calculate GCD of 427, 305, 815, 649 using LCM Formula
Given numbers are 427, 305, 815, 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, 305) = 2135
GCD(427, 305) = ( 427 x 305 ) / 2135
= 427 / 305
= 427
Step2:
LCM(61, 815) = 49715
GCD(61, 815) = ( 61 x 815 ) / 49715
= 61 / 815
= 61
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 427, 305, 815, 649 is 1
