Given numbers are 989,822,921,351,884
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,822,921,351,884 is 992821705668.
Find LCM of 989,822,921,351,884 with Prime Factorization
| 2 | 989, 822, 921, 351, 884 |
| 3 | 989, 411, 921, 351, 442 |
| 13 | 989, 137, 307, 117, 442 |
| 989, 137, 307, 9, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 989 x 137 x 307 x 9 x 34 = 992821705668
Therefore, the lowest common multiple of 989,822,921,351,884 is 992821705668.
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.
989 x 822 x 921 x 351 x 884 = 232320279126312
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.
989 : 1, 23, 43, 989
822 : 1, 2, 3, 6, 137, 274, 411, 822
921 : 1, 3, 307, 921
351 : 1, 3, 9, 13, 27, 39, 117, 351
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,822,921,351,884, is 1.
Now, the common factors can be found like this.
989:23x 43
822:2x 3x 137
921:3x 307
351:3x 3x 3x 13
884:2x 2x 13x 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 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 232320279126312/(1x234)
LCM = 232320279126312/234
LCM = 992821705668
Thus, we can understand that the LCM of 989,822,921,351,884 is 992821705668.
