Find LCM of 989,428,642,897,297 with Prime Factorization
| 2 | 989, 428, 642, 897, 297 |
| 3 | 989, 214, 321, 897, 297 |
| 23 | 989, 214, 107, 299, 99 |
| 107 | 43, 214, 107, 13, 99 |
| 43, 2, 1, 13, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 107 x 43 x 2 x 1 x 13 x 99 = 1634330412
Therefore, the lowest common multiple of 989,428,642,897,297 is 1634330412.
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 428 x 642 x 897 x 297 = 72397568590776
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
428 : 1, 2, 4, 107, 214, 428
642 : 1, 2, 3, 6, 107, 214, 321, 642
897 : 1, 3, 13, 23, 39, 69, 299, 897
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,428,642,897,297, is 1.
Now, the common factors can be found like this.
989:23x 43
428:2x 2x 107
642:2x 3x 107
897:3x 13x 23
297:3x 3x 3x 11
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 23x 107 = 44298
Therefore, the value for common factors is 44298.
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 = 72397568590776/(1x44298)
LCM = 72397568590776/44298
LCM = 1634330412
Thus, we can understand that the LCM of 989,428,642,897,297 is 1634330412.
