Given numbers are 173,168,726,430
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,168,726,430 is 756099960.
Find LCM of 173,168,726,430 with Prime Factorization
| 2 | 173, 168, 726, 430 |
| 3 | 173, 84, 363, 215 |
| 173, 28, 121, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 173 x 28 x 121 x 215 = 756099960
Therefore, the lowest common multiple of 173,168,726,430 is 756099960.
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.
173 x 168 x 726 x 430 = 9073199520
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.
173 : 1, 173
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,168,726,430, is 1.
Now, the common factors can be found like this.
173:173
168:2x 2x 2x 3x 7
726:2x 3x 11x 11
430:2x 5x 43
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 3 = 12
Therefore, the value for common factors is 12.
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 = 9073199520/(1x12)
LCM = 9073199520/12
LCM = 756099960
Thus, we can understand that the LCM of 173,168,726,430 is 756099960.
