Given numbers are 247,646,973,115,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,646,973,115,102 is 2819082630.
Find LCM of 247,646,973,115,102 with Prime Factorization
| 2 | 247, 646, 973, 115, 102 |
| 17 | 247, 323, 973, 115, 51 |
| 19 | 247, 19, 973, 115, 3 |
| 13, 1, 973, 115, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 13 x 1 x 973 x 115 x 3 = 2819082630
Therefore, the lowest common multiple of 247,646,973,115,102 is 2819082630.
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.
247 x 646 x 973 x 115 x 102 = 1821127378980
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.
247 : 1, 13, 19, 247
646 : 1, 2, 17, 19, 34, 38, 323, 646
973 : 1, 7, 139, 973
115 : 1, 5, 23, 115
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,646,973,115,102, is 1.
Now, the common factors can be found like this.
247:13x 19
646:2x 17x 19
973:7x 139
115:5x 23
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 1821127378980/(1x646)
LCM = 1821127378980/646
LCM = 2819082630
Thus, we can understand that the LCM of 247,646,973,115,102 is 2819082630.
