Given numbers are 730, 120, 765, 139

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 139 are 139

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

Given numbers are 730, 120, 765, 139

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

Apply this formula for all numbers.

Step1:

LCM(730, 120) = 8760

GCD(730, 120) = ( 730 x 120 ) / 8760

= 730 / 120

= 730

Step2:

LCM(10, 765) = 1530

GCD(10, 765) = ( 10 x 765 ) / 1530

= 10 / 765

= 10

Step3:

LCM(5, 139) = 695

GCD(5, 139) = ( 5 x 139 ) / 695

= 5 / 139

= 5

So, Greatest Common Divisor of 730, 120, 765, 139 is 1
