Given numbers are 401, 670, 209, 828

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 670 are 2 x 5 x 67

Prime factors of 209 are 11 x 19

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 401, 670, 209, 828

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

Apply this formula for all numbers.

Step1:

LCM(401, 670) = 268670

GCD(401, 670) = ( 401 x 670 ) / 268670

= 401 / 670

= 401

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 401, 670, 209, 828 is 1
