Given numbers are 898,346,660,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,346,660,865 is 51266820.
Find LCM of 898,346,660,865 with Prime Factorization
| 2 | 898, 346, 660, 865 |
| 5 | 449, 173, 330, 865 |
| 173 | 449, 173, 66, 173 |
| 449, 1, 66, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 173 x 449 x 1 x 66 x 1 = 51266820
Therefore, the lowest common multiple of 898,346,660,865 is 51266820.
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.
898 x 346 x 660 x 865 = 177383197200
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.
898 : 1, 2, 449, 898
346 : 1, 2, 173, 346
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,346,660,865, is 1.
Now, the common factors can be found like this.
898:2x 449
346:2x 173
660:2x 2x 3x 5x 11
865:5x 173
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 5x 173 = 3460
Therefore, the value for common factors is 3460.
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 = 177383197200/(1x3460)
LCM = 177383197200/3460
LCM = 51266820
Thus, we can understand that the LCM of 898,346,660,865 is 51266820.
