The list of prime factors of all numbers are

Prime factors of 763 are 7 x 109

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 609 are 3 x 7 x 29

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

Given numbers are 763, 644, 990, 609

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

Apply this formula for all numbers.

Step1:

LCM(763, 644) = 70196

GCD(763, 644) = ( 763 x 644 ) / 70196

= 763 / 644

= 763

Step2:

LCM(7, 990) = 6930

GCD(7, 990) = ( 7 x 990 ) / 6930

= 7 / 990

= 7

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 763, 644, 990, 609 is 1
