Given numbers are 914,152,646,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,152,646,556 is 164143432.
Find LCM of 914,152,646,556 with Prime Factorization
| 2 | 914, 152, 646, 556 |
| 2 | 457, 76, 323, 278 |
| 19 | 457, 38, 323, 139 |
| 457, 2, 17, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 457 x 2 x 17 x 139 = 164143432
Therefore, the lowest common multiple of 914,152,646,556 is 164143432.
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.
914 x 152 x 646 x 556 = 49899603328
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.
914 : 1, 2, 457, 914
152 : 1, 2, 4, 8, 19, 38, 76, 152
646 : 1, 2, 17, 19, 34, 38, 323, 646
556 : 1, 2, 4, 139, 278, 556
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 914,152,646,556, is 2.
Now, the common factors can be found like this.
914:2x 457
152:2x 2x 2x 19
646:2x 17x 19
556:2x 2x 139
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 19 = 152
Therefore, the value for common factors is 152.
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 = 49899603328/(2x152)
LCM = 49899603328/304
LCM = 164143432
Thus, we can understand that the LCM of 914,152,646,556 is 164143432.
