Given numbers are 640, 689, 700, 271

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 689 are 13 x 53

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 271 are 271

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

Given numbers are 640, 689, 700, 271

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

Apply this formula for all numbers.

Step1:

LCM(640, 689) = 440960

GCD(640, 689) = ( 640 x 689 ) / 440960

= 640 / 689

= 640

Step2:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 640, 689, 700, 271 is 1
