Given numbers are 487,294,388,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,294,388,417 is 3860937948.
Find LCM of 487,294,388,417 with Prime Factorization
| 2 | 487, 294, 388, 417 |
| 3 | 487, 147, 194, 417 |
| 487, 49, 194, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 487 x 49 x 194 x 139 = 3860937948
Therefore, the lowest common multiple of 487,294,388,417 is 3860937948.
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.
487 x 294 x 388 x 417 = 23165627688
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.
487 : 1, 487
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
388 : 1, 2, 4, 97, 194, 388
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,294,388,417, is 1.
Now, the common factors can be found like this.
487:487
294:2x 3x 7x 7
388:2x 2x 97
417:3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 23165627688/(1x6)
LCM = 23165627688/6
LCM = 3860937948
Thus, we can understand that the LCM of 487,294,388,417 is 3860937948.
