Given numbers are 770, 305, 651, 272

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 305 are 5 x 61

Prime factors of 651 are 3 x 7 x 31

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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

Given numbers are 770, 305, 651, 272

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

Apply this formula for all numbers.

Step1:

LCM(770, 305) = 46970

GCD(770, 305) = ( 770 x 305 ) / 46970

= 770 / 305

= 770

Step2:

LCM(5, 651) = 3255

GCD(5, 651) = ( 5 x 651 ) / 3255

= 5 / 651

= 5

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 770, 305, 651, 272 is 1
