Given numbers are 105, 145, 240, 136

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 145 are 5 x 29

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

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

Given numbers are 105, 145, 240, 136

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

Apply this formula for all numbers.

Step1:

LCM(105, 145) = 3045

GCD(105, 145) = ( 105 x 145 ) / 3045

= 105 / 145

= 105

Step2:

LCM(5, 240) = 240

GCD(5, 240) = ( 5 x 240 ) / 240

= 5 / 240

= 5

Step3:

LCM(5, 136) = 680

GCD(5, 136) = ( 5 x 136 ) / 680

= 5 / 136

= 5

So, Greatest Common Divisor of 105, 145, 240, 136 is 1
