Given numbers are 173,969,825,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,969,825,220 is 184400700.
Find LCM of 173,969,825,220 with Prime Factorization
| 3 | 173, 969, 825, 220 |
| 5 | 173, 323, 275, 220 |
| 11 | 173, 323, 55, 44 |
| 173, 323, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 173 x 323 x 5 x 4 = 184400700
Therefore, the lowest common multiple of 173,969,825,220 is 184400700.
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 969 x 825 x 220 = 30426115500
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
969 : 1, 3, 17, 19, 51, 57, 323, 969
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,969,825,220, is 1.
Now, the common factors can be found like this.
173:173
969:3x 17x 19
825:3x 5x 5x 11
220:2x 2x 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.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 30426115500/(1x165)
LCM = 30426115500/165
LCM = 184400700
Thus, we can understand that the LCM of 173,969,825,220 is 184400700.
