Given numbers are 885, 644, 990, 510

The list of prime factors of all numbers are

Prime factors of 885 are 3 x 5 x 59

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

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 510 are 2 x 3 x 5 x 17

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

Given numbers are 885, 644, 990, 510

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

Apply this formula for all numbers.

Step1:

LCM(885, 644) = 569940

GCD(885, 644) = ( 885 x 644 ) / 569940

= 885 / 644

= 885

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

So, Greatest Common Divisor of 885, 644, 990, 510 is 1
