Given numbers are 660, 705, 551, 520

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 705 are 3 x 5 x 47

Prime factors of 551 are 19 x 29

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

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

Given numbers are 660, 705, 551, 520

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

Apply this formula for all numbers.

Step1:

LCM(660, 705) = 31020

GCD(660, 705) = ( 660 x 705 ) / 31020

= 660 / 705

= 660

Step2:

LCM(15, 551) = 8265

GCD(15, 551) = ( 15 x 551 ) / 8265

= 15 / 551

= 15

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 660, 705, 551, 520 is 1
