Given numbers are 530,400,646,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,400,646,915 is 1253110800.
Find LCM of 530,400,646,915 with Prime Factorization
| 2 | 530, 400, 646, 915 |
| 5 | 265, 200, 323, 915 |
| 53, 40, 323, 183 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 53 x 40 x 323 x 183 = 1253110800
Therefore, the lowest common multiple of 530,400,646,915 is 1253110800.
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.
530 x 400 x 646 x 915 = 125311080000
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
646 : 1, 2, 17, 19, 34, 38, 323, 646
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,400,646,915, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
400:2x 2x 2x 2x 5x 5
646:2x 17x 19
915:3x 5x 61
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 125311080000/(1x100)
LCM = 125311080000/100
LCM = 1253110800
Thus, we can understand that the LCM of 530,400,646,915 is 1253110800.
