Given numbers are 385, 254, 280

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 254 are 2 x 127

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 385, 254, 280

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

Apply this formula for all numbers.

Step1:

LCM(385, 254) = 97790

GCD(385, 254) = ( 385 x 254 ) / 97790

= 385 / 254

= 385

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 385, 254, 280 is 1
