Given numbers are 515,416,831,412
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,416,831,412 is 178033440.
Find LCM of 515,416,831,412 with Prime Factorization
| 2 | 515, 416, 831, 412 |
| 2 | 515, 208, 831, 206 |
| 103 | 515, 104, 831, 103 |
| 5, 104, 831, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 103 x 5 x 104 x 831 x 1 = 178033440
Therefore, the lowest common multiple of 515,416,831,412 is 178033440.
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 416 x 831 x 412 = 73349777280
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
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
831 : 1, 3, 277, 831
412 : 1, 2, 4, 103, 206, 412
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,416,831,412, is 1.
Now, the common factors can be found like this.
515:5x 103
416:2x 2x 2x 2x 2x 13
831:3x 277
412:2x 2x 103
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 103 = 412
Therefore, the value for common factors is 412.
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 = 73349777280/(1x412)
LCM = 73349777280/412
LCM = 178033440
Thus, we can understand that the LCM of 515,416,831,412 is 178033440.
