Given numbers are 215, 905, 648, 835

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 905 are 5 x 181

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 835 are 5 x 167

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

Given numbers are 215, 905, 648, 835

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

Apply this formula for all numbers.

Step1:

LCM(215, 905) = 38915

GCD(215, 905) = ( 215 x 905 ) / 38915

= 215 / 905

= 215

Step2:

LCM(5, 648) = 3240

GCD(5, 648) = ( 5 x 648 ) / 3240

= 5 / 648

= 5

Step3:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 215, 905, 648, 835 is 1
