Given numbers are 882,669,342,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 882,669,342,855 is 18685170.
Find LCM of 882,669,342,855 with Prime Factorization
| 2 | 882, 669, 342, 855 |
| 3 | 441, 669, 171, 855 |
| 3 | 147, 223, 57, 285 |
| 19 | 49, 223, 19, 95 |
| 49, 223, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 49 x 223 x 1 x 5 = 18685170
Therefore, the lowest common multiple of 882,669,342,855 is 18685170.
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.
882 x 669 x 342 x 855 = 172538859780
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
669 : 1, 3, 223, 669
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,669,342,855, is 3.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
669:3x 223
342:2x 3x 3x 19
855:3x 3x 5x 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 3x 3x 3x 3x 19 = 3078
Therefore, the value for common factors is 3078.
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 = 172538859780/(3x3078)
LCM = 172538859780/9234
LCM = 18685170
Thus, we can understand that the LCM of 882,669,342,855 is 18685170.
