Steps to Calculate GCD of 105, 921, 395, 447 using LCM Formula
Given numbers are 105, 921, 395, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 921) = 32235
GCD(105, 921) = ( 105 x 921 ) / 32235
= 105 / 921
= 105
Step2:
LCM(3, 395) = 1185
GCD(3, 395) = ( 3 x 395 ) / 1185
= 3 / 395
= 3
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 105, 921, 395, 447 is 1
