Find LCM of 441,490,940,984,989 with Prime Factorization
| 2 | 441, 490, 940, 984, 989 |
| 2 | 441, 245, 470, 492, 989 |
| 3 | 441, 245, 235, 246, 989 |
| 5 | 147, 245, 235, 82, 989 |
| 7 | 147, 49, 47, 82, 989 |
| 7 | 21, 7, 47, 82, 989 |
| 3, 1, 47, 82, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 7 x 3 x 1 x 47 x 82 x 989 = 33618364920
Therefore, the lowest common multiple of 441,490,940,984,989 is 33618364920.
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.
441 x 490 x 940 x 984 x 989 = 197675985729600
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,490,940,984,989, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
490:2x 5x 7x 7
940:2x 2x 5x 47
984:2x 2x 2x 3x 41
989:23x 43
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 3x 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 197675985729600/(1x5880)
LCM = 197675985729600/5880
LCM = 33618364920
Thus, we can understand that the LCM of 441,490,940,984,989 is 33618364920.
