Given numbers are 233,684,221,940,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 233,684,221,940,974 is 4030891607340.
Find LCM of 233,684,221,940,974 with Prime Factorization
| 2 | 233, 684, 221, 940, 974 |
| 2 | 233, 342, 221, 470, 487 |
| 233, 171, 221, 235, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 233 x 171 x 221 x 235 x 487 = 4030891607340
Therefore, the lowest common multiple of 233,684,221,940,974 is 4030891607340.
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.
233 x 684 x 221 x 940 x 974 = 32247132858720
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.
233 : 1, 233
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
221 : 1, 13, 17, 221
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 233,684,221,940,974, is 1.
Now, the common factors can be found like this.
233:233
684:2x 2x 3x 3x 19
221:13x 17
940:2x 2x 5x 47
974:2x 487
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 2 = 8
Therefore, the value for common factors is 8.
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 = 32247132858720/(1x8)
LCM = 32247132858720/8
LCM = 4030891607340
Thus, we can understand that the LCM of 233,684,221,940,974 is 4030891607340.
