Steps to Calculate GCD of 447, 978, 648, 424 using LCM Formula
Given numbers are 447, 978, 648, 424
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 978) = 145722
GCD(447, 978) = ( 447 x 978 ) / 145722
= 447 / 978
= 447
Step2:
LCM(3, 648) = 648
GCD(3, 648) = ( 3 x 648 ) / 648
= 3 / 648
= 3
Step3:
LCM(3, 424) = 1272
GCD(3, 424) = ( 3 x 424 ) / 1272
= 3 / 424
= 3
So, Greatest Common Divisor of 447, 978, 648, 424 is 1
