Given numbers are 947,979,356,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,979,356,891 is 300384612.
Find LCM of 947,979,356,891 with Prime Factorization
| 11 | 947, 979, 356, 891 |
| 89 | 947, 89, 356, 81 |
| 947, 1, 4, 81 |
Multiply the prime numbers at the bottom and the left side.
11 x 89 x 947 x 1 x 4 x 81 = 300384612
Therefore, the lowest common multiple of 947,979,356,891 is 300384612.
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.
947 x 979 x 356 x 891 = 294076535148
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.
947 : 1, 947
979 : 1, 11, 89, 979
356 : 1, 2, 4, 89, 178, 356
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,979,356,891, is 1.
Now, the common factors can be found like this.
947:947
979:11x 89
356:2x 2x 89
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 89 = 979
Therefore, the value for common factors is 979.
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 = 294076535148/(1x979)
LCM = 294076535148/979
LCM = 300384612
Thus, we can understand that the LCM of 947,979,356,891 is 300384612.
