Find LCM of 746,420,884,442,753 with Prime Factorization
| 2 | 746, 420, 884, 442, 753 |
| 2 | 373, 210, 442, 221, 753 |
| 3 | 373, 105, 221, 221, 753 |
| 13 | 373, 35, 221, 221, 251 |
| 17 | 373, 35, 17, 17, 251 |
| 373, 35, 1, 1, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 17 x 373 x 35 x 1 x 1 x 251 = 8690086860
Therefore, the lowest common multiple of 746,420,884,442,753 is 8690086860.
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.
746 x 420 x 884 x 442 x 753 = 92184441410880
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.
746 : 1, 2, 373, 746
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
442 : 1, 2, 13, 17, 26, 34, 221, 442
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,420,884,442,753, is 1.
Now, the common factors can be found like this.
746:2x 373
420:2x 2x 3x 5x 7
884:2x 2x 13x 17
442:2x 13x 17
753:3x 251
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 3x 13x 17 = 10608
Therefore, the value for common factors is 10608.
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 = 92184441410880/(1x10608)
LCM = 92184441410880/10608
LCM = 8690086860
Thus, we can understand that the LCM of 746,420,884,442,753 is 8690086860.
