Given numbers are 473,105,638,221,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,105,638,221,905 is 115225680570.
Find LCM of 473,105,638,221,905 with Prime Factorization
| 5 | 473, 105, 638, 221, 905 |
| 11 | 473, 21, 638, 221, 181 |
| 43, 21, 58, 221, 181 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 43 x 21 x 58 x 221 x 181 = 115225680570
Therefore, the lowest common multiple of 473,105,638,221,905 is 115225680570.
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.
473 x 105 x 638 x 221 x 905 = 6337412431350
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.
473 : 1, 11, 43, 473
105 : 1, 3, 5, 7, 15, 21, 35, 105
638 : 1, 2, 11, 22, 29, 58, 319, 638
221 : 1, 13, 17, 221
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,105,638,221,905, is 1.
Now, the common factors can be found like this.
473:11x 43
105:3x 5x 7
638:2x 11x 29
221:13x 17
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.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 6337412431350/(1x55)
LCM = 6337412431350/55
LCM = 115225680570
Thus, we can understand that the LCM of 473,105,638,221,905 is 115225680570.
