Given numbers are 946,571,686,434,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,571,686,434,816 is 2343382711824.
Find LCM of 946,571,686,434,816 with Prime Factorization
| 2 | 946, 571, 686, 434, 816 |
| 7 | 473, 571, 343, 217, 408 |
| 473, 571, 49, 31, 408 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 473 x 571 x 49 x 31 x 408 = 2343382711824
Therefore, the lowest common multiple of 946,571,686,434,816 is 2343382711824.
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 571 x 686 x 434 x 816 = 131229431862144
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
571 : 1, 571
686 : 1, 2, 7, 14, 49, 98, 343, 686
434 : 1, 2, 7, 14, 31, 62, 217, 434
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,571,686,434,816, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
571:571
686:2x 7x 7x 7
434:2x 7x 31
816:2x 2x 2x 2x 3x 17
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 7 = 56
Therefore, the value for common factors is 56.
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 = 131229431862144/(1x56)
LCM = 131229431862144/56
LCM = 2343382711824
Thus, we can understand that the LCM of 946,571,686,434,816 is 2343382711824.
