Given numbers are 140, 418, 287, 578

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 418 are 2 x 11 x 19

Prime factors of 287 are 7 x 41

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 140, 418, 287, 578

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

Apply this formula for all numbers.

Step1:

LCM(140, 418) = 29260

GCD(140, 418) = ( 140 x 418 ) / 29260

= 140 / 418

= 140

Step2:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 140, 418, 287, 578 is 1
