Given numbers are 771, 247, 216, 728

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 247 are 13 x 19

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

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

Given numbers are 771, 247, 216, 728

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

Apply this formula for all numbers.

Step1:

LCM(771, 247) = 190437

GCD(771, 247) = ( 771 x 247 ) / 190437

= 771 / 247

= 771

Step2:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 771, 247, 216, 728 is 1
