Given numbers are 862,715,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,715,880 is 4930640.
Find LCM of 862,715,880 with Prime Factorization
| 2 | 862, 715, 880 |
| 5 | 431, 715, 440 |
| 11 | 431, 143, 88 |
| 431, 13, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 431 x 13 x 8 = 4930640
Therefore, the lowest common multiple of 862,715,880 is 4930640.
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.
862 x 715 x 880 = 542370400
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.
862 : 1, 2, 431, 862
715 : 1, 5, 11, 13, 55, 65, 143, 715
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,715,880, is 1.
Now, the common factors can be found like this.
862:2x 431
715:5x 11x 13
880:2x 2x 2x 2x 5x 11
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 11 = 110
Therefore, the value for common factors is 110.
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 = 542370400/(1x110)
LCM = 542370400/110
LCM = 4930640
Thus, we can understand that the LCM of 862,715,880 is 4930640.
