Given numbers are 139, 551, 765, 648

The list of prime factors of all numbers are

Prime factors of 139 are 139

Prime factors of 551 are 19 x 29

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

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 139, 551, 765, 648

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

Apply this formula for all numbers.

Step1:

LCM(139, 551) = 76589

GCD(139, 551) = ( 139 x 551 ) / 76589

= 139 / 551

= 139

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 139, 551, 765, 648 is 1
