Given numbers are 741, 649, 520, 393

The list of prime factors of all numbers are

Prime factors of 741 are 3 x 13 x 19

Prime factors of 649 are 11 x 59

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 393 are 3 x 131

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

Given numbers are 741, 649, 520, 393

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

Apply this formula for all numbers.

Step1:

LCM(741, 649) = 480909

GCD(741, 649) = ( 741 x 649 ) / 480909

= 741 / 649

= 741

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 741, 649, 520, 393 is 1
