Find LCM of 748,819,884,477,646 with Prime Factorization
| 2 | 748, 819, 884, 477, 646 |
| 2 | 374, 819, 442, 477, 323 |
| 3 | 187, 819, 221, 477, 323 |
| 3 | 187, 273, 221, 159, 323 |
| 13 | 187, 91, 221, 53, 323 |
| 17 | 187, 7, 17, 53, 323 |
| 11, 7, 1, 53, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 17 x 11 x 7 x 1 x 53 x 19 = 616900284
Therefore, the lowest common multiple of 748,819,884,477,646 is 616900284.
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.
748 x 819 x 884 x 477 x 646 = 166873994423136
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
477 : 1, 3, 9, 53, 159, 477
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,819,884,477,646, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
819:3x 3x 7x 13
884:2x 2x 13x 17
477:3x 3x 53
646:2x 17x 19
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 3x 3x 13x 17x 17 = 270504
Therefore, the value for common factors is 270504.
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 = 166873994423136/(1x270504)
LCM = 166873994423136/270504
LCM = 616900284
Thus, we can understand that the LCM of 748,819,884,477,646 is 616900284.
