Given numbers are 960, 670, 640, 217

The list of prime factors of all numbers are

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 670 are 2 x 5 x 67

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

Prime factors of 217 are 7 x 31

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

Given numbers are 960, 670, 640, 217

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

Apply this formula for all numbers.

Step1:

LCM(960, 670) = 64320

GCD(960, 670) = ( 960 x 670 ) / 64320

= 960 / 670

= 960

Step2:

LCM(10, 640) = 640

GCD(10, 640) = ( 10 x 640 ) / 640

= 10 / 640

= 10

Step3:

LCM(10, 217) = 2170

GCD(10, 217) = ( 10 x 217 ) / 2170

= 10 / 217

= 10

So, Greatest Common Divisor of 960, 670, 640, 217 is 1
