Given numbers are 551, 372, 640, 830

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 551, 372, 640, 830

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

Apply this formula for all numbers.

Step1:

LCM(551, 372) = 204972

GCD(551, 372) = ( 551 x 372 ) / 204972

= 551 / 372

= 551

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 551, 372, 640, 830 is 1
