Given numbers are 403, 990, 523, 402

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 523 are 523

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 403, 990, 523, 402

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

Apply this formula for all numbers.

Step1:

LCM(403, 990) = 398970

GCD(403, 990) = ( 403 x 990 ) / 398970

= 403 / 990

= 403

Step2:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 403, 990, 523, 402 is 1
