Given numbers are 400, 698, 15, 372

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 698 are 2 x 349

Prime factors of 15 are 3 x 5

Prime factors of 372 are 2 x 2 x 3 x 31

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

Given numbers are 400, 698, 15, 372

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

Apply this formula for all numbers.

Step1:

LCM(400, 698) = 139600

GCD(400, 698) = ( 400 x 698 ) / 139600

= 400 / 698

= 400

Step2:

LCM(2, 15) = 30

GCD(2, 15) = ( 2 x 15 ) / 30

= 2 / 15

= 2

Step3:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

So, Greatest Common Divisor of 400, 698, 15, 372 is 1
