Given numbers are 947,816,662,378,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,816,662,378,129 is 692910490608.
Find LCM of 947,816,662,378,129 with Prime Factorization
| 2 | 947, 816, 662, 378, 129 |
| 3 | 947, 408, 331, 189, 129 |
| 947, 136, 331, 63, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 947 x 136 x 331 x 63 x 43 = 692910490608
Therefore, the lowest common multiple of 947,816,662,378,129 is 692910490608.
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 816 x 662 x 378 x 129 = 24944777661888
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
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
662 : 1, 2, 331, 662
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,816,662,378,129, is 1.
Now, the common factors can be found like this.
947:947
816:2x 2x 2x 2x 3x 17
662:2x 331
378:2x 3x 3x 3x 7
129:3x 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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 24944777661888/(1x36)
LCM = 24944777661888/36
LCM = 692910490608
Thus, we can understand that the LCM of 947,816,662,378,129 is 692910490608.
