Given numbers are 113,391,668,220,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 113,391,668,220,946 is 69801187060.
Find LCM of 113,391,668,220,946 with Prime Factorization
| 2 | 113, 391, 668, 220, 946 |
| 2 | 113, 391, 334, 110, 473 |
| 11 | 113, 391, 167, 55, 473 |
| 113, 391, 167, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 113 x 391 x 167 x 5 x 43 = 69801187060
Therefore, the lowest common multiple of 113,391,668,220,946 is 69801187060.
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.
113 x 391 x 668 x 220 x 946 = 6142504461280
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.
113 : 1, 113
391 : 1, 17, 23, 391
668 : 1, 2, 4, 167, 334, 668
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 113,391,668,220,946, is 1.
Now, the common factors can be found like this.
113:113
391:17x 23
668:2x 2x 167
220:2x 2x 5x 11
946:2x 11x 43
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 11 = 88
Therefore, the value for common factors is 88.
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 = 6142504461280/(1x88)
LCM = 6142504461280/88
LCM = 69801187060
Thus, we can understand that the LCM of 113,391,668,220,946 is 69801187060.
