Given numbers are 846,155,836,341,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 846,155,836,341,989 is 54209404260.
Find LCM of 846,155,836,341,989 with Prime Factorization
| 2 | 846, 155, 836, 341, 989 |
| 11 | 423, 155, 418, 341, 989 |
| 31 | 423, 155, 38, 31, 989 |
| 423, 5, 38, 1, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 423 x 5 x 38 x 1 x 989 = 54209404260
Therefore, the lowest common multiple of 846,155,836,341,989 is 54209404260.
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.
846 x 155 x 836 x 341 x 989 = 36970813705320
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
155 : 1, 5, 31, 155
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
341 : 1, 11, 31, 341
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,155,836,341,989, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
155:5x 31
836:2x 2x 11x 19
341:11x 31
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 11x 31 = 682
Therefore, the value for common factors is 682.
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 = 36970813705320/(1x682)
LCM = 36970813705320/682
LCM = 54209404260
Thus, we can understand that the LCM of 846,155,836,341,989 is 54209404260.
