Given numbers are 500, 420, 287, 810
The list of prime factors of all numbers are
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 287 are 7 x 41
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 500, 420, 287, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(500, 420) = 10500
GCD(500, 420) = ( 500 x 420 ) / 10500
= 500 / 420
= 500
Step2:
LCM(20, 287) = 5740
GCD(20, 287) = ( 20 x 287 ) / 5740
= 20 / 287
= 20
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 500, 420, 287, 810 is 1
