Given numbers are 251, 690, 448, 315

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 315 are 3 x 3 x 5 x 7

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

Given numbers are 251, 690, 448, 315

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

Apply this formula for all numbers.

Step1:

LCM(251, 690) = 173190

GCD(251, 690) = ( 251 x 690 ) / 173190

= 251 / 690

= 251

Step2:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 251, 690, 448, 315 is 1
