Given numbers are 287, 490, 551, 447

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 551 are 19 x 29

Prime factors of 447 are 3 x 149

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 287, 490, 551, 447

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

Apply this formula for all numbers.

Step1:

LCM(287, 490) = 20090

GCD(287, 490) = ( 287 x 490 ) / 20090

= 287 / 490

= 287

Step2:

LCM(7, 551) = 3857

GCD(7, 551) = ( 7 x 551 ) / 3857

= 7 / 551

= 7

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 287, 490, 551, 447 is 1
