Given numbers are 640, 275, 272, 411

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 275 are 5 x 5 x 11

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 411 are 3 x 137

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

Given numbers are 640, 275, 272, 411

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

Apply this formula for all numbers.

Step1:

LCM(640, 275) = 35200

GCD(640, 275) = ( 640 x 275 ) / 35200

= 640 / 275

= 640

Step2:

LCM(5, 272) = 1360

GCD(5, 272) = ( 5 x 272 ) / 1360

= 5 / 272

= 5

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 640, 275, 272, 411 is 1
