Given numbers are 644, 386, 488, 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 386 are 2 x 193

Prime factors of 488 are 2 x 2 x 2 x 61

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, 386, 488, 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, 386) = 124292

GCD(644, 386) = ( 644 x 386 ) / 124292

= 644 / 386

= 644

Step2:

LCM(2, 488) = 488

GCD(2, 488) = ( 2 x 488 ) / 488

= 2 / 488

= 2

Step3:

LCM(2, 365) = 730

GCD(2, 365) = ( 2 x 365 ) / 730

= 2 / 365

= 2

So, Greatest Common Divisor of 644, 386, 488, 365 is 1
