Given numbers are 555, 755, 448, 644

The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

Prime factors of 755 are 5 x 151

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

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

Given numbers are 555, 755, 448, 644

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

Apply this formula for all numbers.

Step1:

LCM(555, 755) = 83805

GCD(555, 755) = ( 555 x 755 ) / 83805

= 555 / 755

= 555

Step2:

LCM(5, 448) = 2240

GCD(5, 448) = ( 5 x 448 ) / 2240

= 5 / 448

= 5

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 555, 755, 448, 644 is 1
