Given numbers are 644, 956, 753, 823

The list of prime factors of all numbers are

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

Prime factors of 956 are 2 x 2 x 239

Prime factors of 753 are 3 x 251

Prime factors of 823 are 823

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

Given numbers are 644, 956, 753, 823

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

Apply this formula for all numbers.

Step1:

LCM(644, 956) = 153916

GCD(644, 956) = ( 644 x 956 ) / 153916

= 644 / 956

= 644

Step2:

LCM(4, 753) = 3012

GCD(4, 753) = ( 4 x 753 ) / 3012

= 4 / 753

= 4

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 644, 956, 753, 823 is 1
