Given numbers are 155,209,506,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,209,506,115 is 1490170.
Find LCM of 155,209,506,115 with Prime Factorization
| 5 | 155, 209, 506, 115 |
| 11 | 31, 209, 506, 23 |
| 23 | 31, 19, 46, 23 |
| 31, 19, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 23 x 31 x 19 x 2 x 1 = 1490170
Therefore, the lowest common multiple of 155,209,506,115 is 1490170.
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.
155 x 209 x 506 x 115 = 1885065050
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.
155 : 1, 5, 31, 155
209 : 1, 11, 19, 209
506 : 1, 2, 11, 22, 23, 46, 253, 506
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,209,506,115, is 1.
Now, the common factors can be found like this.
155:5x 31
209:11x 19
506:2x 11x 23
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 23 = 1265
Therefore, the value for common factors is 1265.
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 = 1885065050/(1x1265)
LCM = 1885065050/1265
LCM = 1490170
Thus, we can understand that the LCM of 155,209,506,115 is 1490170.
