Given numbers are 770, 761, 84, 255

The list of prime factors of all numbers are

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

Prime factors of 761 are 761

Prime factors of 84 are 2 x 2 x 3 x 7

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 770, 761, 84, 255

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

Apply this formula for all numbers.

Step1:

LCM(770, 761) = 585970

GCD(770, 761) = ( 770 x 761 ) / 585970

= 770 / 761

= 770

Step2:

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

= 1 / 84

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 770, 761, 84, 255 is 1
