Given numbers are 844,576,638,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,576,638,738 is 1589569344.
Find LCM of 844,576,638,738 with Prime Factorization
| 2 | 844, 576, 638, 738 |
| 2 | 422, 288, 319, 369 |
| 3 | 211, 144, 319, 369 |
| 3 | 211, 48, 319, 123 |
| 211, 16, 319, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 211 x 16 x 319 x 41 = 1589569344
Therefore, the lowest common multiple of 844,576,638,738 is 1589569344.
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.
844 x 576 x 638 x 738 = 228897985536
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.
844 : 1, 2, 4, 211, 422, 844
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
638 : 1, 2, 11, 22, 29, 58, 319, 638
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,576,638,738, is 2.
Now, the common factors can be found like this.
844:2x 2x 211
576:2x 2x 2x 2x 2x 2x 3x 3
638:2x 11x 29
738:2x 3x 3x 41
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 228897985536/(2x72)
LCM = 228897985536/144
LCM = 1589569344
Thus, we can understand that the LCM of 844,576,638,738 is 1589569344.
