Given numbers are 446,285,665,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,285,665,862 is 383490870.
Find LCM of 446,285,665,862 with Prime Factorization
| 2 | 446, 285, 665, 862 |
| 5 | 223, 285, 665, 431 |
| 19 | 223, 57, 133, 431 |
| 223, 3, 7, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 223 x 3 x 7 x 431 = 383490870
Therefore, the lowest common multiple of 446,285,665,862 is 383490870.
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.
446 x 285 x 665 x 862 = 72863265300
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.
446 : 1, 2, 223, 446
285 : 1, 3, 5, 15, 19, 57, 95, 285
665 : 1, 5, 7, 19, 35, 95, 133, 665
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,285,665,862, is 1.
Now, the common factors can be found like this.
446:2x 223
285:3x 5x 19
665:5x 7x 19
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 72863265300/(1x190)
LCM = 72863265300/190
LCM = 383490870
Thus, we can understand that the LCM of 446,285,665,862 is 383490870.
