Given numbers are 705, 220, 294, 640

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 294 are 2 x 3 x 7 x 7

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

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

Given numbers are 705, 220, 294, 640

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

Apply this formula for all numbers.

Step1:

LCM(705, 220) = 31020

GCD(705, 220) = ( 705 x 220 ) / 31020

= 705 / 220

= 705

Step2:

LCM(5, 294) = 1470

GCD(5, 294) = ( 5 x 294 ) / 1470

= 5 / 294

= 5

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 705, 220, 294, 640 is 1
