Given numbers are 399,806,847,362,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,806,847,362,220 is 70432301940.
Find LCM of 399,806,847,362,220 with Prime Factorization
| 2 | 399, 806, 847, 362, 220 |
| 7 | 399, 403, 847, 181, 110 |
| 11 | 57, 403, 121, 181, 110 |
| 57, 403, 11, 181, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 57 x 403 x 11 x 181 x 10 = 70432301940
Therefore, the lowest common multiple of 399,806,847,362,220 is 70432301940.
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.
399 x 806 x 847 x 362 x 220 = 21693148997520
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
806 : 1, 2, 13, 26, 31, 62, 403, 806
847 : 1, 7, 11, 77, 121, 847
362 : 1, 2, 181, 362
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,806,847,362,220, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
806:2x 13x 31
847:7x 11x 11
362:2x 181
220:2x 2x 5x 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 2x 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 21693148997520/(1x308)
LCM = 21693148997520/308
LCM = 70432301940
Thus, we can understand that the LCM of 399,806,847,362,220 is 70432301940.
