Given numbers are 437,646,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,646,248 is 1842392.
Find LCM of 437,646,248 with Prime Factorization
| 2 | 437, 646, 248 |
| 19 | 437, 323, 124 |
| 23, 17, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 17 x 124 = 1842392
Therefore, the lowest common multiple of 437,646,248 is 1842392.
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.
437 x 646 x 248 = 70010896
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.
437 : 1, 19, 23, 437
646 : 1, 2, 17, 19, 34, 38, 323, 646
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,646,248, is 1.
Now, the common factors can be found like this.
437:19x 23
646:2x 17x 19
248:2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 70010896/(1x38)
LCM = 70010896/38
LCM = 1842392
Thus, we can understand that the LCM of 437,646,248 is 1842392.
