Given numbers are 400, 402, 668, 275

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 402 are 2 x 3 x 67

Prime factors of 668 are 2 x 2 x 167

Prime factors of 275 are 5 x 5 x 11

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

Given numbers are 400, 402, 668, 275

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

Apply this formula for all numbers.

Step1:

LCM(400, 402) = 80400

GCD(400, 402) = ( 400 x 402 ) / 80400

= 400 / 402

= 400

Step2:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

Step3:

LCM(2, 275) = 550

GCD(2, 275) = ( 2 x 275 ) / 550

= 2 / 275

= 2

So, Greatest Common Divisor of 400, 402, 668, 275 is 1
