Given numbers are 728, 840, 995, 868

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 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 995 are 5 x 199

Prime factors of 868 are 2 x 2 x 7 x 31

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

Given numbers are 728, 840, 995, 868

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

Apply this formula for all numbers.

Step1:

LCM(728, 840) = 10920

GCD(728, 840) = ( 728 x 840 ) / 10920

= 728 / 840

= 728

Step2:

LCM(56, 995) = 55720

GCD(56, 995) = ( 56 x 995 ) / 55720

= 56 / 995

= 56

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 728, 840, 995, 868 is 1
