Given numbers are 268, 100, 685, 457

The list of prime factors of all numbers are

Prime factors of 268 are 2 x 2 x 67

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 685 are 5 x 137

Prime factors of 457 are 457

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

Given numbers are 268, 100, 685, 457

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

Apply this formula for all numbers.

Step1:

LCM(268, 100) = 6700

GCD(268, 100) = ( 268 x 100 ) / 6700

= 268 / 100

= 268

Step2:

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

= 4 / 685

= 4

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 268, 100, 685, 457 is 1
