Given numbers are 816,913,517,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,913,517,947 is 33159561072.
Find LCM of 816,913,517,947 with Prime Factorization
| 11 | 816, 913, 517, 947 |
| 816, 83, 47, 947 |
Multiply the prime numbers at the bottom and the left side.
11 x 816 x 83 x 47 x 947 = 33159561072
Therefore, the lowest common multiple of 816,913,517,947 is 33159561072.
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.
816 x 913 x 517 x 947 = 364755171792
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
913 : 1, 11, 83, 913
517 : 1, 11, 47, 517
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,913,517,947, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
913:11x 83
517:11x 47
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 364755171792/(1x11)
LCM = 364755171792/11
LCM = 33159561072
Thus, we can understand that the LCM of 816,913,517,947 is 33159561072.
