Given numbers are 644, 758, 312, 513

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 758 are 2 x 379

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 513 are 3 x 3 x 3 x 19

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

Given numbers are 644, 758, 312, 513

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

Apply this formula for all numbers.

Step1:

LCM(644, 758) = 244076

GCD(644, 758) = ( 644 x 758 ) / 244076

= 644 / 758

= 644

Step2:

LCM(2, 312) = 312

GCD(2, 312) = ( 2 x 312 ) / 312

= 2 / 312

= 2

Step3:

LCM(2, 513) = 1026

GCD(2, 513) = ( 2 x 513 ) / 1026

= 2 / 513

= 2

So, Greatest Common Divisor of 644, 758, 312, 513 is 1
