Given numbers are 640, 635, 709, 730

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 635 are 5 x 127

Prime factors of 709 are 709

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 640, 635, 709, 730

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

Apply this formula for all numbers.

Step1:

LCM(640, 635) = 81280

GCD(640, 635) = ( 640 x 635 ) / 81280

= 640 / 635

= 640

Step2:

LCM(5, 709) = 3545

GCD(5, 709) = ( 5 x 709 ) / 3545

= 5 / 709

= 5

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 640, 635, 709, 730 is 1
