Given numbers are 648, 290, 636, 385

The list of prime factors of all numbers are

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

Prime factors of 290 are 2 x 5 x 29

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 648, 290, 636, 385

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

Apply this formula for all numbers.

Step1:

LCM(648, 290) = 93960

GCD(648, 290) = ( 648 x 290 ) / 93960

= 648 / 290

= 648

Step2:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

Step3:

LCM(2, 385) = 770

GCD(2, 385) = ( 2 x 385 ) / 770

= 2 / 385

= 2

So, Greatest Common Divisor of 648, 290, 636, 385 is 1
