Given numbers are 440,782,976,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,782,976,918 is 566699760.
Find LCM of 440,782,976,918 with Prime Factorization
| 2 | 440, 782, 976, 918 |
| 2 | 220, 391, 488, 459 |
| 2 | 110, 391, 244, 459 |
| 17 | 55, 391, 122, 459 |
| 55, 23, 122, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 55 x 23 x 122 x 27 = 566699760
Therefore, the lowest common multiple of 440,782,976,918 is 566699760.
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.
440 x 782 x 976 x 918 = 308284669440
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
782 : 1, 2, 17, 23, 34, 46, 391, 782
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,782,976,918, is 2.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
782:2x 17x 23
976:2x 2x 2x 2x 61
918:2x 3x 3x 3x 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 2x 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 308284669440/(2x272)
LCM = 308284669440/544
LCM = 566699760
Thus, we can understand that the LCM of 440,782,976,918 is 566699760.
