Given numbers are 280, 725, 387, 427

The list of prime factors of all numbers are

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

Prime factors of 725 are 5 x 5 x 29

Prime factors of 387 are 3 x 3 x 43

Prime factors of 427 are 7 x 61

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

Given numbers are 280, 725, 387, 427

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

Apply this formula for all numbers.

Step1:

LCM(280, 725) = 40600

GCD(280, 725) = ( 280 x 725 ) / 40600

= 280 / 725

= 280

Step2:

LCM(5, 387) = 1935

GCD(5, 387) = ( 5 x 387 ) / 1935

= 5 / 387

= 5

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 280, 725, 387, 427 is 1
