Given numbers are 644, 738, 291, 365

The list of prime factors of all numbers are

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

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 291 are 3 x 97

Prime factors of 365 are 5 x 73

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

Given numbers are 644, 738, 291, 365

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

Apply this formula for all numbers.

Step1:

LCM(644, 738) = 237636

GCD(644, 738) = ( 644 x 738 ) / 237636

= 644 / 738

= 644

Step2:

LCM(2, 291) = 582

GCD(2, 291) = ( 2 x 291 ) / 582

= 2 / 291

= 2

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 644, 738, 291, 365 is 1
