Given numbers are 644, 378, 265, 344

The list of prime factors of all numbers are

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

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 265 are 5 x 53

Prime factors of 344 are 2 x 2 x 2 x 43

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

Given numbers are 644, 378, 265, 344

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

Apply this formula for all numbers.

Step1:

LCM(644, 378) = 17388

GCD(644, 378) = ( 644 x 378 ) / 17388

= 644 / 378

= 644

Step2:

LCM(14, 265) = 3710

GCD(14, 265) = ( 14 x 265 ) / 3710

= 14 / 265

= 14

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 644, 378, 265, 344 is 1
