Given numbers are 810, 209, 756, 306
The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 209 are 11 x 19
Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
Prime factors of 306 are 2 x 3 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 209, 756, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 209) = 169290
GCD(810, 209) = ( 810 x 209 ) / 169290
= 810 / 209
= 810
Step2:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 810, 209, 756, 306 is 1
