Given numbers are 515,942,784,952
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,942,784,952 is 3232906320.
Find LCM of 515,942,784,952 with Prime Factorization
| 2 | 515, 942, 784, 952 |
| 2 | 515, 471, 392, 476 |
| 2 | 515, 471, 196, 238 |
| 7 | 515, 471, 98, 119 |
| 515, 471, 14, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 515 x 471 x 14 x 17 = 3232906320
Therefore, the lowest common multiple of 515,942,784,952 is 3232906320.
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.
515 x 942 x 784 x 952 = 362085507840
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.
515 : 1, 5, 103, 515
942 : 1, 2, 3, 6, 157, 314, 471, 942
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,942,784,952, is 1.
Now, the common factors can be found like this.
515:5x 103
942:2x 3x 157
784:2x 2x 2x 2x 7x 7
952:2x 2x 2x 7x 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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 362085507840/(1x112)
LCM = 362085507840/112
LCM = 3232906320
Thus, we can understand that the LCM of 515,942,784,952 is 3232906320.
