Given numbers are 988,862,354,515,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,862,354,515,515 is 38816351340.
Find LCM of 988,862,354,515,515 with Prime Factorization
| 2 | 988, 862, 354, 515, 515 |
| 5 | 494, 431, 177, 515, 515 |
| 103 | 494, 431, 177, 103, 103 |
| 494, 431, 177, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 103 x 494 x 431 x 177 x 1 x 1 = 38816351340
Therefore, the lowest common multiple of 988,862,354,515,515 is 38816351340.
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.
988 x 862 x 354 x 515 x 515 = 79961683760400
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
862 : 1, 2, 431, 862
354 : 1, 2, 3, 6, 59, 118, 177, 354
515 : 1, 5, 103, 515
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,862,354,515,515, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
862:2x 431
354:2x 3x 59
515:5x 103
515:5x 103
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 103 = 2060
Therefore, the value for common factors is 2060.
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 = 79961683760400/(1x2060)
LCM = 79961683760400/2060
LCM = 38816351340
Thus, we can understand that the LCM of 988,862,354,515,515 is 38816351340.
