Given numbers are 402, 870, 245, 211

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 245 are 5 x 7 x 7

Prime factors of 211 are 211

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

Given numbers are 402, 870, 245, 211

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

Apply this formula for all numbers.

Step1:

LCM(402, 870) = 58290

GCD(402, 870) = ( 402 x 870 ) / 58290

= 402 / 870

= 402

Step2:

LCM(6, 245) = 1470

GCD(6, 245) = ( 6 x 245 ) / 1470

= 6 / 245

= 6

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 402, 870, 245, 211 is 1
