Given numbers are 228,988,412,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,988,412,956 is 72964788.
Find LCM of 228,988,412,956 with Prime Factorization
| 2 | 228, 988, 412, 956 |
| 2 | 114, 494, 206, 478 |
| 19 | 57, 247, 103, 239 |
| 3, 13, 103, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 3 x 13 x 103 x 239 = 72964788
Therefore, the lowest common multiple of 228,988,412,956 is 72964788.
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.
228 x 988 x 412 x 956 = 88725182208
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
412 : 1, 2, 4, 103, 206, 412
956 : 1, 2, 4, 239, 478, 956
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,988,412,956, is 4.
Now, the common factors can be found like this.
228:2x 2x 3x 19
988:2x 2x 13x 19
412:2x 2x 103
956:2x 2x 239
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 19 = 304
Therefore, the value for common factors is 304.
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 = 88725182208/(4x304)
LCM = 88725182208/1216
LCM = 72964788
Thus, we can understand that the LCM of 228,988,412,956 is 72964788.
