Prime factors of 513 are 3 x 3 x 3 x 19
Prime factors of 906 are 2 x 3 x 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 815, 765, 513, 906
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 765) = 124695
GCD(815, 765) = ( 815 x 765 ) / 124695
= 815 / 765
= 815
Step2:
LCM(5, 513) = 2565
GCD(5, 513) = ( 5 x 513 ) / 2565
= 5 / 513
= 5
Step3:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
So, Greatest Common Divisor of 815, 765, 513, 906 is 1
