Given numbers are 400, 678, 185, 787

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 678 are 2 x 3 x 113

Prime factors of 185 are 5 x 37

Prime factors of 787 are 787

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

Given numbers are 400, 678, 185, 787

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

Apply this formula for all numbers.

Step1:

LCM(400, 678) = 135600

GCD(400, 678) = ( 400 x 678 ) / 135600

= 400 / 678

= 400

Step2:

LCM(2, 185) = 370

GCD(2, 185) = ( 2 x 185 ) / 370

= 2 / 185

= 2

Step3:

LCM(1, 787) = 787

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

= 1 / 787

= 1

So, Greatest Common Divisor of 400, 678, 185, 787 is 1
