Given numbers are 190, 563, 340, 646

The list of prime factors of all numbers are

Prime factors of 190 are 2 x 5 x 19

Prime factors of 563 are 563

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 190, 563, 340, 646

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

Apply this formula for all numbers.

Step1:

LCM(190, 563) = 106970

GCD(190, 563) = ( 190 x 563 ) / 106970

= 190 / 563

= 190

Step2:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 190, 563, 340, 646 is 1
