Given numbers are 245, 665, 800, 748

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 665 are 5 x 7 x 19

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 748 are 2 x 2 x 11 x 17

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

Given numbers are 245, 665, 800, 748

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

Apply this formula for all numbers.

Step1:

LCM(245, 665) = 4655

GCD(245, 665) = ( 245 x 665 ) / 4655

= 245 / 665

= 245

Step2:

LCM(35, 800) = 5600

GCD(35, 800) = ( 35 x 800 ) / 5600

= 35 / 800

= 35

Step3:

LCM(5, 748) = 3740

GCD(5, 748) = ( 5 x 748 ) / 3740

= 5 / 748

= 5

So, Greatest Common Divisor of 245, 665, 800, 748 is 1
