Given numbers are 406, 380, 447, 787

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 447 are 3 x 149

Prime factors of 787 are 787

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

Given numbers are 406, 380, 447, 787

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

Apply this formula for all numbers.

Step1:

LCM(406, 380) = 77140

GCD(406, 380) = ( 406 x 380 ) / 77140

= 406 / 380

= 406

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 406, 380, 447, 787 is 1
