Steps to Calculate GCD of 441, 447, 345, 251 using LCM Formula
Given numbers are 441, 447, 345, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 447) = 65709
GCD(441, 447) = ( 441 x 447 ) / 65709
= 441 / 447
= 441
Step2:
LCM(3, 345) = 345
GCD(3, 345) = ( 3 x 345 ) / 345
= 3 / 345
= 3
Step3:
LCM(3, 251) = 753
GCD(3, 251) = ( 3 x 251 ) / 753
= 3 / 251
= 3
So, Greatest Common Divisor of 441, 447, 345, 251 is 1
