Given numbers are 720, 731, 245, 436

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 731 are 17 x 43

Prime factors of 245 are 5 x 7 x 7

Prime factors of 436 are 2 x 2 x 109

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

Given numbers are 720, 731, 245, 436

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

Apply this formula for all numbers.

Step1:

LCM(720, 731) = 526320

GCD(720, 731) = ( 720 x 731 ) / 526320

= 720 / 731

= 720

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 720, 731, 245, 436 is 1
