Given numbers are 840, 513, 865, 330
The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 513 are 3 x 3 x 3 x 19
Prime factors of 865 are 5 x 173
Prime factors of 330 are 2 x 3 x 5 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 513, 865, 330
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 513) = 143640
GCD(840, 513) = ( 840 x 513 ) / 143640
= 840 / 513
= 840
Step2:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
Step3:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
So, Greatest Common Divisor of 840, 513, 865, 330 is 1
