Given numbers are 286,782,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,782,505 is 56472130.
Find LCM of 286,782,505 with Prime Factorization
| 2 | 286, 782, 505 |
| 143, 391, 505 |
Multiply the prime numbers at the bottom and the left side.
2 x 143 x 391 x 505 = 56472130
Therefore, the lowest common multiple of 286,782,505 is 56472130.
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.
286 x 782 x 505 = 112944260
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
782 : 1, 2, 17, 23, 34, 46, 391, 782
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,782,505, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
782:2x 17x 23
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 112944260/(1x2)
LCM = 112944260/2
LCM = 56472130
Thus, we can understand that the LCM of 286,782,505 is 56472130.
