The LCM of 420,229,771,845,413 is 246465770460.
Find LCM of 420,229,771,845,413 with Prime Factorization
| 3 | 420, 229, 771, 845, 413 |
| 5 | 140, 229, 257, 845, 413 |
| 7 | 28, 229, 257, 169, 413 |
| 4, 229, 257, 169, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 4 x 229 x 257 x 169 x 59 = 246465770460
Therefore, the lowest common multiple of 420,229,771,845,413 is 246465770460.
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.
420 x 229 x 771 x 845 x 413 = 25878905898300
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.
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
229 : 1, 229
771 : 1, 3, 257, 771
845 : 1, 5, 13, 65, 169, 845
413 : 1, 7, 59, 413
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,229,771,845,413, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
229:229
771:3x 257
845:5x 13x 13
413:7x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 25878905898300/(1x105)
LCM = 25878905898300/105
LCM = 246465770460
Thus, we can understand that the LCM of 420,229,771,845,413 is 246465770460.
