Given numbers are 312,666,837,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,666,837,442 is 54753192.
Find LCM of 312,666,837,442 with Prime Factorization
| 2 | 312, 666, 837, 442 |
| 3 | 156, 333, 837, 221 |
| 3 | 52, 111, 279, 221 |
| 13 | 52, 37, 93, 221 |
| 4, 37, 93, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 4 x 37 x 93 x 17 = 54753192
Therefore, the lowest common multiple of 312,666,837,442 is 54753192.
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.
312 x 666 x 837 x 442 = 76873481568
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
837 : 1, 3, 9, 27, 31, 93, 279, 837
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,666,837,442, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
666:2x 3x 3x 37
837:3x 3x 3x 31
442:2x 13x 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 3x 3x 3x 13 = 1404
Therefore, the value for common factors is 1404.
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 = 76873481568/(1x1404)
LCM = 76873481568/1404
LCM = 54753192
Thus, we can understand that the LCM of 312,666,837,442 is 54753192.
