Given numbers are 400, 838, 87

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 838 are 2 x 419

Prime factors of 87 are 3 x 29

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

Given numbers are 400, 838, 87

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

Apply this formula for all numbers.

Step1:

LCM(400, 838) = 167600

GCD(400, 838) = ( 400 x 838 ) / 167600

= 400 / 838

= 400

Step2:

LCM(2, 87) = 174

GCD(2, 87) = ( 2 x 87 ) / 174

= 2 / 87

= 2

So, Greatest Common Divisor of 400, 838, 87 is 1
