Given numbers are 386, 787, 138, 480

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 787 are 787

Prime factors of 138 are 2 x 3 x 23

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 386, 787, 138, 480

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

Apply this formula for all numbers.

Step1:

LCM(386, 787) = 303782

GCD(386, 787) = ( 386 x 787 ) / 303782

= 386 / 787

= 386

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 386, 787, 138, 480 is 1
