Given numbers are 685, 240, 851, 919

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

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

Prime factors of 851 are 23 x 37

Prime factors of 919 are 919

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

Given numbers are 685, 240, 851, 919

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

Apply this formula for all numbers.

Step1:

LCM(685, 240) = 32880

GCD(685, 240) = ( 685 x 240 ) / 32880

= 685 / 240

= 685

Step2:

LCM(5, 851) = 4255

GCD(5, 851) = ( 5 x 851 ) / 4255

= 5 / 851

= 5

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 685, 240, 851, 919 is 1
