Given numbers are 457, 745, 693, 240

The list of prime factors of all numbers are

Prime factors of 457 are 457

Prime factors of 745 are 5 x 149

Prime factors of 693 are 3 x 3 x 7 x 11

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

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

Given numbers are 457, 745, 693, 240

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

Apply this formula for all numbers.

Step1:

LCM(457, 745) = 340465

GCD(457, 745) = ( 457 x 745 ) / 340465

= 457 / 745

= 457

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 457, 745, 693, 240 is 1
