Given numbers are 180,694,724,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,694,724,905 is 11305260.
Find LCM of 180,694,724,905 with Prime Factorization
| 2 | 180, 694, 724, 905 |
| 2 | 90, 347, 362, 905 |
| 5 | 45, 347, 181, 905 |
| 181 | 9, 347, 181, 181 |
| 9, 347, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 181 x 9 x 347 x 1 x 1 = 11305260
Therefore, the lowest common multiple of 180,694,724,905 is 11305260.
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.
180 x 694 x 724 x 905 = 81850082400
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
694 : 1, 2, 347, 694
724 : 1, 2, 4, 181, 362, 724
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,694,724,905, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
694:2x 347
724:2x 2x 181
905:5x 181
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 2x 5x 181 = 7240
Therefore, the value for common factors is 7240.
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 = 81850082400/(1x7240)
LCM = 81850082400/7240
LCM = 11305260
Thus, we can understand that the LCM of 180,694,724,905 is 11305260.
