The LCM of 258,473,665,949,968 is 78804846120.
Find LCM of 258,473,665,949,968 with Prime Factorization
| 2 | 258, 473, 665, 949, 968 |
| 11 | 129, 473, 665, 949, 484 |
| 43 | 129, 43, 665, 949, 44 |
| 3, 1, 665, 949, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 3 x 1 x 665 x 949 x 44 = 78804846120
Therefore, the lowest common multiple of 258,473,665,949,968 is 78804846120.
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.
258 x 473 x 665 x 949 x 968 = 74549384429520
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
473 : 1, 11, 43, 473
665 : 1, 5, 7, 19, 35, 95, 133, 665
949 : 1, 13, 73, 949
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,473,665,949,968, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
473:11x 43
665:5x 7x 19
949:13x 73
968:2x 2x 2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 43 = 946
Therefore, the value for common factors is 946.
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 = 74549384429520/(1x946)
LCM = 74549384429520/946
LCM = 78804846120
Thus, we can understand that the LCM of 258,473,665,949,968 is 78804846120.
