Given numbers are 409, 805, 660, 982

The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 805 are 5 x 7 x 23

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 982 are 2 x 491

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

Given numbers are 409, 805, 660, 982

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

Apply this formula for all numbers.

Step1:

LCM(409, 805) = 329245

GCD(409, 805) = ( 409 x 805 ) / 329245

= 409 / 805

= 409

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 982) = 982

GCD(1, 982) = ( 1 x 982 ) / 982

= 1 / 982

= 1

So, Greatest Common Divisor of 409, 805, 660, 982 is 1
