Given numbers are 856, 204, 980, 215

The list of prime factors of all numbers are

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 215 are 5 x 43

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

Given numbers are 856, 204, 980, 215

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

Apply this formula for all numbers.

Step1:

LCM(856, 204) = 43656

GCD(856, 204) = ( 856 x 204 ) / 43656

= 856 / 204

= 856

Step2:

LCM(4, 980) = 980

GCD(4, 980) = ( 4 x 980 ) / 980

= 4 / 980

= 4

Step3:

LCM(4, 215) = 860

GCD(4, 215) = ( 4 x 215 ) / 860

= 4 / 215

= 4

So, Greatest Common Divisor of 856, 204, 980, 215 is 1
