Given numbers are 447, 402, 27, 831

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(447, 402) = 59898

GCD(447, 402) = ( 447 x 402 ) / 59898

= 447 / 402

= 447

Step2:

LCM(3, 27) = 27

GCD(3, 27) = ( 3 x 27 ) / 27

= 3 / 27

= 3

Step3:

LCM(3, 831) = 831

GCD(3, 831) = ( 3 x 831 ) / 831

= 3 / 831

= 3

So, Greatest Common Divisor of 447, 402, 27, 831 is 3
