Given numbers are 770, 276, 255, 990

The list of prime factors of all numbers are

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

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 255 are 3 x 5 x 17

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 770, 276, 255, 990

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

Apply this formula for all numbers.

Step1:

LCM(770, 276) = 106260

GCD(770, 276) = ( 770 x 276 ) / 106260

= 770 / 276

= 770

Step2:

LCM(2, 255) = 510

GCD(2, 255) = ( 2 x 255 ) / 510

= 2 / 255

= 2

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 770, 276, 255, 990 is 1
