Given numbers are 644, 575, 831, 386

The list of prime factors of all numbers are

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

Prime factors of 575 are 5 x 5 x 23

Prime factors of 831 are 3 x 277

Prime factors of 386 are 2 x 193

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

Given numbers are 644, 575, 831, 386

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

Apply this formula for all numbers.

Step1:

LCM(644, 575) = 16100

GCD(644, 575) = ( 644 x 575 ) / 16100

= 644 / 575

= 644

Step2:

LCM(23, 831) = 19113

GCD(23, 831) = ( 23 x 831 ) / 19113

= 23 / 831

= 23

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 644, 575, 831, 386 is 1
