Given numbers are 401, 158, 784, 630

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 158 are 2 x 79

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 401, 158, 784, 630

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

Apply this formula for all numbers.

Step1:

LCM(401, 158) = 63358

GCD(401, 158) = ( 401 x 158 ) / 63358

= 401 / 158

= 401

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 401, 158, 784, 630 is 1
