Given numbers are 986,715,242,428,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,715,242,428,288 is 119487345120.
Find LCM of 986,715,242,428,288 with Prime Factorization
| 2 | 986, 715, 242, 428, 288 |
| 2 | 493, 715, 121, 214, 144 |
| 11 | 493, 715, 121, 107, 72 |
| 493, 65, 11, 107, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 493 x 65 x 11 x 107 x 72 = 119487345120
Therefore, the lowest common multiple of 986,715,242,428,288 is 119487345120.
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.
986 x 715 x 242 x 428 x 288 = 21029772741120
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
715 : 1, 5, 11, 13, 55, 65, 143, 715
242 : 1, 2, 11, 22, 121, 242
428 : 1, 2, 4, 107, 214, 428
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,715,242,428,288, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
715:5x 11x 13
242:2x 11x 11
428:2x 2x 107
288:2x 2x 2x 2x 2x 3x 3
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 21029772741120/(1x176)
LCM = 21029772741120/176
LCM = 119487345120
Thus, we can understand that the LCM of 986,715,242,428,288 is 119487345120.
