Given numbers are 640, 109, 530, 276

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 109 are 109

Prime factors of 530 are 2 x 5 x 53

Prime factors of 276 are 2 x 2 x 3 x 23

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

Given numbers are 640, 109, 530, 276

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

Apply this formula for all numbers.

Step1:

LCM(640, 109) = 69760

GCD(640, 109) = ( 640 x 109 ) / 69760

= 640 / 109

= 640

Step2:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

Step3:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

So, Greatest Common Divisor of 640, 109, 530, 276 is 1
