Given numbers are 240, 721, 750, 780

The list of prime factors of all numbers are

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

Prime factors of 721 are 7 x 103

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 240, 721, 750, 780

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

Apply this formula for all numbers.

Step1:

LCM(240, 721) = 173040

GCD(240, 721) = ( 240 x 721 ) / 173040

= 240 / 721

= 240

Step2:

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

= 1 / 750

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 240, 721, 750, 780 is 1
