Given numbers are 645, 196, 880, 199

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 199 are 199

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

Given numbers are 645, 196, 880, 199

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

Apply this formula for all numbers.

Step1:

LCM(645, 196) = 126420

GCD(645, 196) = ( 645 x 196 ) / 126420

= 645 / 196

= 645

Step2:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

Step3:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 645, 196, 880, 199 is 1
