Given numbers are 718,192,835,221,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,192,835,221,990 is 419747739840.
Find LCM of 718,192,835,221,990 with Prime Factorization
| 2 | 718, 192, 835, 221, 990 |
| 3 | 359, 96, 835, 221, 495 |
| 5 | 359, 32, 835, 221, 165 |
| 359, 32, 167, 221, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 359 x 32 x 167 x 221 x 33 = 419747739840
Therefore, the lowest common multiple of 718,192,835,221,990 is 419747739840.
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.
718 x 192 x 835 x 221 x 990 = 25184864390400
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.
718 : 1, 2, 359, 718
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
835 : 1, 5, 167, 835
221 : 1, 13, 17, 221
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,192,835,221,990, is 1.
Now, the common factors can be found like this.
718:2x 359
192:2x 2x 2x 2x 2x 2x 3
835:5x 167
221:13x 17
990:2x 3x 3x 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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 25184864390400/(1x60)
LCM = 25184864390400/60
LCM = 419747739840
Thus, we can understand that the LCM of 718,192,835,221,990 is 419747739840.
