Given numbers are 785, 644, 900, 513

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

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

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

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 785, 644, 900, 513

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

Apply this formula for all numbers.

Step1:

LCM(785, 644) = 505540

GCD(785, 644) = ( 785 x 644 ) / 505540

= 785 / 644

= 785

Step2:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 785, 644, 900, 513 is 1
