Given numbers are 441, 447, 396, 665
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, 396) = 396
GCD(3, 396) = ( 3 x 396 ) / 396
= 3 / 396
= 3
Step3:
LCM(3, 665) = 1995
GCD(3, 665) = ( 3 x 665 ) / 1995
= 3 / 665
= 3
So, Greatest Common Divisor of 441, 447, 396, 665 is 1
