Given numbers are 154,661,858,149,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,661,858,149,330 is 2957624670.
Find LCM of 154,661,858,149,330 with Prime Factorization
| 2 | 154, 661, 858, 149, 330 |
| 3 | 77, 661, 429, 149, 165 |
| 11 | 77, 661, 143, 149, 55 |
| 7, 661, 13, 149, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 7 x 661 x 13 x 149 x 5 = 2957624670
Therefore, the lowest common multiple of 154,661,858,149,330 is 2957624670.
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.
154 x 661 x 858 x 149 x 330 = 4294471020840
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
661 : 1, 661
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
149 : 1, 149
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,661,858,149,330, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
661:661
858:2x 3x 11x 13
149:149
330:2x 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 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 = 4294471020840/(1x1452)
LCM = 4294471020840/1452
LCM = 2957624670
Thus, we can understand that the LCM of 154,661,858,149,330 is 2957624670.
