Given numbers are 721,290,884,219,888
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,290,884,219,888 is 1497722542680.
Find LCM of 721,290,884,219,888 with Prime Factorization
| 2 | 721, 290, 884, 219, 888 |
| 2 | 721, 145, 442, 219, 444 |
| 3 | 721, 145, 221, 219, 222 |
| 721, 145, 221, 73, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 721 x 145 x 221 x 73 x 74 = 1497722542680
Therefore, the lowest common multiple of 721,290,884,219,888 is 1497722542680.
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.
721 x 290 x 884 x 219 x 888 = 35945341024320
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.
721 : 1, 7, 103, 721
290 : 1, 2, 5, 10, 29, 58, 145, 290
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
219 : 1, 3, 73, 219
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,290,884,219,888, is 1.
Now, the common factors can be found like this.
721:7x 103
290:2x 5x 29
884:2x 2x 13x 17
219:3x 73
888:2x 2x 2x 3x 37
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 3 = 24
Therefore, the value for common factors is 24.
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 = 35945341024320/(1x24)
LCM = 35945341024320/24
LCM = 1497722542680
Thus, we can understand that the LCM of 721,290,884,219,888 is 1497722542680.
