Given numbers are 11, 89, 85, 40

The list of prime factors of all numbers are

Prime factors of 11 are 11

Prime factors of 89 are 89

Prime factors of 85 are 5 x 17

Prime factors of 40 are 2 x 2 x 2 x 5

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

Given numbers are 11, 89, 85, 40

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

Apply this formula for all numbers.

Step1:

LCM(11, 89) = 979

GCD(11, 89) = ( 11 x 89 ) / 979

= 11 / 89

= 11

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

Step3:

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

= 1 / 40

= 1

So, Greatest Common Divisor of 11, 89, 85, 40 is 1
