Steps to Calculate GCD of 447, 665, 603, 145 using LCM Formula
Given numbers are 447, 665, 603, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 665) = 297255
GCD(447, 665) = ( 447 x 665 ) / 297255
= 447 / 665
= 447
Step2:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 447, 665, 603, 145 is 1
