Given numbers are 946,678,451,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,678,451,989 is 302414442.
Find LCM of 946,678,451,989 with Prime Factorization
| 2 | 946, 678, 451, 989 |
| 11 | 473, 339, 451, 989 |
| 43 | 43, 339, 41, 989 |
| 1, 339, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 1 x 339 x 41 x 23 = 302414442
Therefore, the lowest common multiple of 946,678,451,989 is 302414442.
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.
946 x 678 x 451 x 989 = 286084062132
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
678 : 1, 2, 3, 6, 113, 226, 339, 678
451 : 1, 11, 41, 451
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,678,451,989, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
678:2x 3x 113
451:11x 41
989:23x 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 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 = 286084062132/(1x946)
LCM = 286084062132/946
LCM = 302414442
Thus, we can understand that the LCM of 946,678,451,989 is 302414442.
