Given numbers are 637, 414, 305, 320

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 414 are 2 x 3 x 3 x 23

Prime factors of 305 are 5 x 61

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 637, 414, 305, 320

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

Apply this formula for all numbers.

Step1:

LCM(637, 414) = 263718

GCD(637, 414) = ( 637 x 414 ) / 263718

= 637 / 414

= 637

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 637, 414, 305, 320 is 1
