Steps to Calculate GCD of 447, 343, 649, 285 using LCM Formula
Given numbers are 447, 343, 649, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 343) = 153321
GCD(447, 343) = ( 447 x 343 ) / 153321
= 447 / 343
= 447
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 447, 343, 649, 285 is 1
