Find LCM of 845,400,572,889,257 with Prime Factorization
| 2 | 845, 400, 572, 889, 257 |
| 2 | 845, 200, 286, 889, 257 |
| 5 | 845, 100, 143, 889, 257 |
| 13 | 169, 20, 143, 889, 257 |
| 13, 20, 11, 889, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 13 x 20 x 11 x 889 x 257 = 169892522800
Therefore, the lowest common multiple of 845,400,572,889,257 is 169892522800.
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.
845 x 400 x 572 x 889 x 257 = 44172055928000
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.
845 : 1, 5, 13, 65, 169, 845
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
889 : 1, 7, 127, 889
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,400,572,889,257, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
400:2x 2x 2x 2x 5x 5
572:2x 2x 11x 13
889:7x 127
257:257
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 44172055928000/(1x260)
LCM = 44172055928000/260
LCM = 169892522800
Thus, we can understand that the LCM of 845,400,572,889,257 is 169892522800.
