Given numbers are 637, 871, 285, 450

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 871 are 13 x 67

Prime factors of 285 are 3 x 5 x 19

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 637, 871, 285, 450

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

Apply this formula for all numbers.

Step1:

LCM(637, 871) = 42679

GCD(637, 871) = ( 637 x 871 ) / 42679

= 637 / 871

= 637

Step2:

LCM(13, 285) = 3705

GCD(13, 285) = ( 13 x 285 ) / 3705

= 13 / 285

= 13

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 637, 871, 285, 450 is 1
