Given numbers are 621, 747, 300, 860

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 747 are 3 x 3 x 83

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 621, 747, 300, 860

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

Apply this formula for all numbers.

Step1:

LCM(621, 747) = 51543

GCD(621, 747) = ( 621 x 747 ) / 51543

= 621 / 747

= 621

Step2:

LCM(9, 300) = 900

GCD(9, 300) = ( 9 x 300 ) / 900

= 9 / 300

= 9

Step3:

LCM(3, 860) = 2580

GCD(3, 860) = ( 3 x 860 ) / 2580

= 3 / 860

= 3

So, Greatest Common Divisor of 621, 747, 300, 860 is 1
