Given numbers are 447,117,221,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,117,221,520 is 11854440.
Find LCM of 447,117,221,520 with Prime Factorization
| 3 | 447, 117, 221, 520 |
| 13 | 149, 39, 221, 520 |
| 149, 3, 17, 40 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 149 x 3 x 17 x 40 = 11854440
Therefore, the lowest common multiple of 447,117,221,520 is 11854440.
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.
447 x 117 x 221 x 520 = 6010201080
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.
447 : 1, 3, 149, 447
117 : 1, 3, 9, 13, 39, 117
221 : 1, 13, 17, 221
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,117,221,520, is 1.
Now, the common factors can be found like this.
447:3x 149
117:3x 3x 13
221:13x 17
520:2x 2x 2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 6010201080/(1x507)
LCM = 6010201080/507
LCM = 11854440
Thus, we can understand that the LCM of 447,117,221,520 is 11854440.
