Given numbers are 490, 257, 815, 954

The list of prime factors of all numbers are

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

Prime factors of 257 are 257

Prime factors of 815 are 5 x 163

Prime factors of 954 are 2 x 3 x 3 x 53

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

Given numbers are 490, 257, 815, 954

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

Apply this formula for all numbers.

Step1:

LCM(490, 257) = 125930

GCD(490, 257) = ( 490 x 257 ) / 125930

= 490 / 257

= 490

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

So, Greatest Common Divisor of 490, 257, 815, 954 is 1
