Given numbers are 210, 145, 829, 445

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 145 are 5 x 29

Prime factors of 829 are 829

Prime factors of 445 are 5 x 89

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

Given numbers are 210, 145, 829, 445

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

Apply this formula for all numbers.

Step1:

LCM(210, 145) = 6090

GCD(210, 145) = ( 210 x 145 ) / 6090

= 210 / 145

= 210

Step2:

LCM(5, 829) = 4145

GCD(5, 829) = ( 5 x 829 ) / 4145

= 5 / 829

= 5

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 210, 145, 829, 445 is 1
