Given numbers are 640, 286, 707, 223

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 286 are 2 x 11 x 13

Prime factors of 707 are 7 x 101

Prime factors of 223 are 223

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

Given numbers are 640, 286, 707, 223

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

Apply this formula for all numbers.

Step1:

LCM(640, 286) = 91520

GCD(640, 286) = ( 640 x 286 ) / 91520

= 640 / 286

= 640

Step2:

LCM(2, 707) = 1414

GCD(2, 707) = ( 2 x 707 ) / 1414

= 2 / 707

= 2

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 640, 286, 707, 223 is 1
