Given numbers are 551, 878, 507, 720

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 878 are 2 x 439

Prime factors of 507 are 3 x 13 x 13

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 551, 878, 507, 720

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

Apply this formula for all numbers.

Step1:

LCM(551, 878) = 483778

GCD(551, 878) = ( 551 x 878 ) / 483778

= 551 / 878

= 551

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 551, 878, 507, 720 is 1
