Given numbers are 440,338,986,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,338,986,255 is 109978440.
Find LCM of 440,338,986,255 with Prime Factorization
| 2 | 440, 338, 986, 255 |
| 5 | 220, 169, 493, 255 |
| 17 | 44, 169, 493, 51 |
| 44, 169, 29, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 44 x 169 x 29 x 3 = 109978440
Therefore, the lowest common multiple of 440,338,986,255 is 109978440.
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 338 x 986 x 255 = 37392669600
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
338 : 1, 2, 13, 26, 169, 338
986 : 1, 2, 17, 29, 34, 58, 493, 986
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,338,986,255, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
338:2x 13x 13
986:2x 17x 29
255:3x 5x 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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 37392669600/(1x340)
LCM = 37392669600/340
LCM = 109978440
Thus, we can understand that the LCM of 440,338,986,255 is 109978440.
