Given numbers are 424,390,130,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,390,130,432 is 1488240.
Find LCM of 424,390,130,432 with Prime Factorization
| 2 | 424, 390, 130, 432 |
| 2 | 212, 195, 65, 216 |
| 2 | 106, 195, 65, 108 |
| 3 | 53, 195, 65, 54 |
| 5 | 53, 65, 65, 18 |
| 13 | 53, 13, 13, 18 |
| 53, 1, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 53 x 1 x 1 x 18 = 1488240
Therefore, the lowest common multiple of 424,390,130,432 is 1488240.
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.
424 x 390 x 130 x 432 = 9286617600
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
130 : 1, 2, 5, 10, 13, 26, 65, 130
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,390,130,432, is 2.
Now, the common factors can be found like this.
424:2x 2x 2x 53
390:2x 3x 5x 13
130:2x 5x 13
432:2x 2x 2x 2x 3x 3x 3
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 2x 3x 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 9286617600/(2x3120)
LCM = 9286617600/6240
LCM = 1488240
Thus, we can understand that the LCM of 424,390,130,432 is 1488240.
