Find LCM of 646,836,874,596,865 with Prime Factorization
2 | 646, 836, 874, 596, 865 |
2 | 323, 418, 437, 298, 865 |
19 | 323, 209, 437, 149, 865 |
17, 11, 23, 149, 865 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 17 x 11 x 23 x 149 x 865 = 42129413260
Therefore, the lowest common multiple of 646,836,874,596,865 is 42129413260.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
646 x 836 x 874 x 596 x 865 = 243339490989760
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
646 : 1, 2, 17, 19, 34, 38, 323, 646
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
874 : 1, 2, 19, 23, 38, 46, 437, 874
596 : 1, 2, 4, 149, 298, 596
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,836,874,596,865, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
836:2x 2x 11x 19
874:2x 19x 23
596:2x 2x 149
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 19x 19 = 5776
Therefore, the value for common factors is 5776.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 243339490989760/(1x5776)
LCM = 243339490989760/5776
LCM = 42129413260
Thus, we can understand that the LCM of 646,836,874,596,865 is 42129413260.
