Given numbers are 240,524,393,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,524,393,428 is 3364080.
Find LCM of 240,524,393,428 with Prime Factorization
| 2 | 240, 524, 393, 428 |
| 2 | 120, 262, 393, 214 |
| 3 | 60, 131, 393, 107 |
| 131 | 20, 131, 131, 107 |
| 20, 1, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 131 x 20 x 1 x 1 x 107 = 3364080
Therefore, the lowest common multiple of 240,524,393,428 is 3364080.
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.
240 x 524 x 393 x 428 = 21153335040
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
524 : 1, 2, 4, 131, 262, 524
393 : 1, 3, 131, 393
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,524,393,428, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
524:2x 2x 131
393:3x 131
428:2x 2x 107
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 131 = 6288
Therefore, the value for common factors is 6288.
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 = 21153335040/(1x6288)
LCM = 21153335040/6288
LCM = 3364080
Thus, we can understand that the LCM of 240,524,393,428 is 3364080.
