Given numbers are 4,638,408,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4,638,408,308 is 911064.
Find LCM of 4,638,408,308 with Prime Factorization
2 | 4, 638, 408, 308 |
2 | 2, 319, 204, 154 |
11 | 1, 319, 102, 77 |
1, 29, 102, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 1 x 29 x 102 x 7 = 911064
Therefore, the lowest common multiple of 4,638,408,308 is 911064.
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.
4 x 638 x 408 x 308 = 320694528
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.
4 : 1, 2, 4
638 : 1, 2, 11, 22, 29, 58, 319, 638
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,638,408,308, is 2.
Now, the common factors can be found like this.
4:2x 2
638:2x 11x 29
408:2x 2x 2x 3x 17
308:2x 2x 7x 11
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 11 = 176
Therefore, the value for common factors is 176.
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 = 320694528/(2x176)
LCM = 320694528/352
LCM = 911064
Thus, we can understand that the LCM of 4,638,408,308 is 911064.
