Given numbers are 693, 400, 250, 987

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

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

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 693, 400, 250, 987

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

Apply this formula for all numbers.

Step1:

LCM(693, 400) = 277200

GCD(693, 400) = ( 693 x 400 ) / 277200

= 693 / 400

= 693

Step2:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 693, 400, 250, 987 is 1
