Given numbers are 680, 216, 530, 217

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 530 are 2 x 5 x 53

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 680, 216, 530, 217

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

Apply this formula for all numbers.

Step1:

LCM(680, 216) = 18360

GCD(680, 216) = ( 680 x 216 ) / 18360

= 680 / 216

= 680

Step2:

LCM(8, 530) = 2120

GCD(8, 530) = ( 8 x 530 ) / 2120

= 8 / 530

= 8

Step3:

LCM(2, 217) = 434

GCD(2, 217) = ( 2 x 217 ) / 434

= 2 / 217

= 2

So, Greatest Common Divisor of 680, 216, 530, 217 is 1
