Given numbers are 660,622,159,143,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,622,159,143,418 is 2687058660.
Find LCM of 660,622,159,143,418 with Prime Factorization
| 2 | 660, 622, 159, 143, 418 |
| 3 | 330, 311, 159, 143, 209 |
| 11 | 110, 311, 53, 143, 209 |
| 10, 311, 53, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 10 x 311 x 53 x 13 x 19 = 2687058660
Therefore, the lowest common multiple of 660,622,159,143,418 is 2687058660.
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.
660 x 622 x 159 x 143 x 418 = 3901609174320
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.
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
622 : 1, 2, 311, 622
159 : 1, 3, 53, 159
143 : 1, 11, 13, 143
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,622,159,143,418, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
622:2x 311
159:3x 53
143:11x 13
418:2x 11x 19
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 11x 11 = 1452
Therefore, the value for common factors is 1452.
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 = 3901609174320/(1x1452)
LCM = 3901609174320/1452
LCM = 2687058660
Thus, we can understand that the LCM of 660,622,159,143,418 is 2687058660.
