Given numbers are 640, 800, 907, 687

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 907 are 907

Prime factors of 687 are 3 x 229

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

Given numbers are 640, 800, 907, 687

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

Apply this formula for all numbers.

Step1:

LCM(640, 800) = 3200

GCD(640, 800) = ( 640 x 800 ) / 3200

= 640 / 800

= 640

Step2:

LCM(160, 907) = 145120

GCD(160, 907) = ( 160 x 907 ) / 145120

= 160 / 907

= 160

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 640, 800, 907, 687 is 1
