Given numbers are 662,856,993,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,856,993,805 is 684256440.
Find LCM of 662,856,993,805 with Prime Factorization
| 2 | 662, 856, 993, 805 |
| 331 | 331, 428, 993, 805 |
| 1, 428, 3, 805 |
Multiply the prime numbers at the bottom and the left side.
2 x 331 x 1 x 428 x 3 x 805 = 684256440
Therefore, the lowest common multiple of 662,856,993,805 is 684256440.
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.
662 x 856 x 993 x 805 = 452977763280
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.
662 : 1, 2, 331, 662
856 : 1, 2, 4, 8, 107, 214, 428, 856
993 : 1, 3, 331, 993
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,856,993,805, is 1.
Now, the common factors can be found like this.
662:2x 331
856:2x 2x 2x 107
993:3x 331
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 331 = 662
Therefore, the value for common factors is 662.
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 = 452977763280/(1x662)
LCM = 452977763280/662
LCM = 684256440
Thus, we can understand that the LCM of 662,856,993,805 is 684256440.
