Given numbers are 387, 340, 235, 280

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 235 are 5 x 47

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 387, 340, 235, 280

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

Apply this formula for all numbers.

Step1:

LCM(387, 340) = 131580

GCD(387, 340) = ( 387 x 340 ) / 131580

= 387 / 340

= 387

Step2:

LCM(1, 235) = 235

GCD(1, 235) = ( 1 x 235 ) / 235

= 1 / 235

= 1

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 387, 340, 235, 280 is 1
