Given numbers are 728, 776, 570, 505

The list of prime factors of all numbers are

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 776 are 2 x 2 x 2 x 97

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 505 are 5 x 101

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

Given numbers are 728, 776, 570, 505

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

Apply this formula for all numbers.

Step1:

LCM(728, 776) = 70616

GCD(728, 776) = ( 728 x 776 ) / 70616

= 728 / 776

= 728

Step2:

LCM(8, 570) = 2280

GCD(8, 570) = ( 8 x 570 ) / 2280

= 8 / 570

= 8

Step3:

LCM(2, 505) = 1010

GCD(2, 505) = ( 2 x 505 ) / 1010

= 2 / 505

= 2

So, Greatest Common Divisor of 728, 776, 570, 505 is 1
