Given numbers are 491, 540, 193, 630

The list of prime factors of all numbers are

Prime factors of 491 are 491

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 193 are 193

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 491, 540, 193, 630

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

Apply this formula for all numbers.

Step1:

LCM(491, 540) = 265140

GCD(491, 540) = ( 491 x 540 ) / 265140

= 491 / 540

= 491

Step2:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 491, 540, 193, 630 is 1
