Given numbers are 642,110,648,105,477
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,110,648,105,477 is 1414801080.
Find LCM of 642,110,648,105,477 with Prime Factorization
| 2 | 642, 110, 648, 105, 477 |
| 3 | 321, 55, 324, 105, 477 |
| 3 | 107, 55, 108, 35, 159 |
| 5 | 107, 55, 36, 35, 53 |
| 107, 11, 36, 7, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 107 x 11 x 36 x 7 x 53 = 1414801080
Therefore, the lowest common multiple of 642,110,648,105,477 is 1414801080.
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.
642 x 110 x 648 x 105 x 477 = 2291977749600
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
110 : 1, 2, 5, 10, 11, 22, 55, 110
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
105 : 1, 3, 5, 7, 15, 21, 35, 105
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,110,648,105,477, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
110:2x 5x 11
648:2x 2x 2x 3x 3x 3x 3
105:3x 5x 7
477:3x 3x 53
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 3x 3x 3x 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 2291977749600/(1x1620)
LCM = 2291977749600/1620
LCM = 1414801080
Thus, we can understand that the LCM of 642,110,648,105,477 is 1414801080.
