Given numbers are 665, 660, 429, 551

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 429 are 3 x 11 x 13

Prime factors of 551 are 19 x 29

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

Given numbers are 665, 660, 429, 551

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

Apply this formula for all numbers.

Step1:

LCM(665, 660) = 87780

GCD(665, 660) = ( 665 x 660 ) / 87780

= 665 / 660

= 665

Step2:

LCM(5, 429) = 2145

GCD(5, 429) = ( 5 x 429 ) / 2145

= 5 / 429

= 5

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 665, 660, 429, 551 is 1
