Given numbers are 635,419,120,724,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,419,120,724,442 is 255428785560.
Find LCM of 635,419,120,724,442 with Prime Factorization
| 2 | 635, 419, 120, 724, 442 |
| 2 | 635, 419, 60, 362, 221 |
| 5 | 635, 419, 30, 181, 221 |
| 127, 419, 6, 181, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 127 x 419 x 6 x 181 x 221 = 255428785560
Therefore, the lowest common multiple of 635,419,120,724,442 is 255428785560.
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.
635 x 419 x 120 x 724 x 442 = 10217151422400
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.
635 : 1, 5, 127, 635
419 : 1, 419
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
724 : 1, 2, 4, 181, 362, 724
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,419,120,724,442, is 1.
Now, the common factors can be found like this.
635:5x 127
419:419
120:2x 2x 2x 3x 5
724:2x 2x 181
442:2x 13x 17
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 5 = 40
Therefore, the value for common factors is 40.
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 = 10217151422400/(1x40)
LCM = 10217151422400/40
LCM = 255428785560
Thus, we can understand that the LCM of 635,419,120,724,442 is 255428785560.
