Given numbers are 680, 856, 215, 352

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 856 are 2 x 2 x 2 x 107

Prime factors of 215 are 5 x 43

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

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

Given numbers are 680, 856, 215, 352

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

Apply this formula for all numbers.

Step1:

LCM(680, 856) = 72760

GCD(680, 856) = ( 680 x 856 ) / 72760

= 680 / 856

= 680

Step2:

LCM(8, 215) = 1720

GCD(8, 215) = ( 8 x 215 ) / 1720

= 8 / 215

= 8

Step3:

LCM(1, 352) = 352

GCD(1, 352) = ( 1 x 352 ) / 352

= 1 / 352

= 1

So, Greatest Common Divisor of 680, 856, 215, 352 is 1
