Given numbers are 640, 196, 705, 294

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 196 are 2 x 2 x 7 x 7

Prime factors of 705 are 3 x 5 x 47

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

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

Given numbers are 640, 196, 705, 294

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

Apply this formula for all numbers.

Step1:

LCM(640, 196) = 31360

GCD(640, 196) = ( 640 x 196 ) / 31360

= 640 / 196

= 640

Step2:

LCM(4, 705) = 2820

GCD(4, 705) = ( 4 x 705 ) / 2820

= 4 / 705

= 4

Step3:

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

= 1 / 294

= 1

So, Greatest Common Divisor of 640, 196, 705, 294 is 1
