Given numbers are 105, 136, 640, 918

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 136 are 2 x 2 x 2 x 17

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

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Given numbers are 105, 136, 640, 918

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

Apply this formula for all numbers.

Step1:

LCM(105, 136) = 14280

GCD(105, 136) = ( 105 x 136 ) / 14280

= 105 / 136

= 105

Step2:

LCM(1, 640) = 640

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

= 1 / 640

= 1

Step3:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

So, Greatest Common Divisor of 105, 136, 640, 918 is 1
