Given numbers are 400, 987, 607, 618

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 987 are 3 x 7 x 47

Prime factors of 607 are 607

Prime factors of 618 are 2 x 3 x 103

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

Given numbers are 400, 987, 607, 618

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

Apply this formula for all numbers.

Step1:

LCM(400, 987) = 394800

GCD(400, 987) = ( 400 x 987 ) / 394800

= 400 / 987

= 400

Step2:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

Step3:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 400, 987, 607, 618 is 1
