Given numbers are 287, 270, 373, 680

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 373 are 373

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 287, 270, 373, 680

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

Apply this formula for all numbers.

Step1:

LCM(287, 270) = 77490

GCD(287, 270) = ( 287 x 270 ) / 77490

= 287 / 270

= 287

Step2:

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

= 1 / 373

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 287, 270, 373, 680 is 1
