Given numbers are 761, 840, 255, 247

The list of prime factors of all numbers are

Prime factors of 761 are 761

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 255 are 3 x 5 x 17

Prime factors of 247 are 13 x 19

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

Given numbers are 761, 840, 255, 247

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

Apply this formula for all numbers.

Step1:

LCM(761, 840) = 639240

GCD(761, 840) = ( 761 x 840 ) / 639240

= 761 / 840

= 761

Step2:

LCM(1, 255) = 255

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

= 1 / 255

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 761, 840, 255, 247 is 1
