Given numbers are 533, 391, 780, 407

The list of prime factors of all numbers are

Prime factors of 533 are 13 x 41

Prime factors of 391 are 17 x 23

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

Prime factors of 407 are 11 x 37

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

Given numbers are 533, 391, 780, 407

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

Apply this formula for all numbers.

Step1:

LCM(533, 391) = 208403

GCD(533, 391) = ( 533 x 391 ) / 208403

= 533 / 391

= 533

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 533, 391, 780, 407 is 1
