Given numbers are 490,339,973,894,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,339,973,894,678 is 3440304210.
Find LCM of 490,339,973,894,678 with Prime Factorization
| 2 | 490, 339, 973, 894, 678 |
| 3 | 245, 339, 973, 447, 339 |
| 7 | 245, 113, 973, 149, 113 |
| 113 | 35, 113, 139, 149, 113 |
| 35, 1, 139, 149, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 113 x 35 x 1 x 139 x 149 x 1 = 3440304210
Therefore, the lowest common multiple of 490,339,973,894,678 is 3440304210.
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.
490 x 339 x 973 x 894 x 678 = 97966102683960
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
339 : 1, 3, 113, 339
973 : 1, 7, 139, 973
894 : 1, 2, 3, 6, 149, 298, 447, 894
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,339,973,894,678, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
339:3x 113
973:7x 139
894:2x 3x 149
678:2x 3x 113
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 113 = 28476
Therefore, the value for common factors is 28476.
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 = 97966102683960/(1x28476)
LCM = 97966102683960/28476
LCM = 3440304210
Thus, we can understand that the LCM of 490,339,973,894,678 is 3440304210.
