Given numbers are 154,660,942,882
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,660,942,882 is 15232140.
Find LCM of 154,660,942,882 with Prime Factorization
| 2 | 154, 660, 942, 882 |
| 3 | 77, 330, 471, 441 |
| 7 | 77, 110, 157, 147 |
| 11 | 11, 110, 157, 21 |
| 1, 10, 157, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 10 x 157 x 21 = 15232140
Therefore, the lowest common multiple of 154,660,942,882 is 15232140.
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 660 x 942 x 882 = 84446984160
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
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,660,942,882, is 2.
Now, the common factors can be found like this.
154:2x 7x 11
660:2x 2x 3x 5x 11
942:2x 3x 157
882:2x 3x 3x 7x 7
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 3x 7x 11 = 2772
Therefore, the value for common factors is 2772.
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 = 84446984160/(2x2772)
LCM = 84446984160/5544
LCM = 15232140
Thus, we can understand that the LCM of 154,660,942,882 is 15232140.
