Given numbers are 551, 230, 387, 620

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 230 are 2 x 5 x 23

Prime factors of 387 are 3 x 3 x 43

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 551, 230, 387, 620

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

Apply this formula for all numbers.

Step1:

LCM(551, 230) = 126730

GCD(551, 230) = ( 551 x 230 ) / 126730

= 551 / 230

= 551

Step2:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 551, 230, 387, 620 is 1
