Given numbers are 468,780,932,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,780,932,956 is 130307580.
Find LCM of 468,780,932,956 with Prime Factorization
| 2 | 468, 780, 932, 956 |
| 2 | 234, 390, 466, 478 |
| 3 | 117, 195, 233, 239 |
| 13 | 39, 65, 233, 239 |
| 3, 5, 233, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 3 x 5 x 233 x 239 = 130307580
Therefore, the lowest common multiple of 468,780,932,956 is 130307580.
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.
468 x 780 x 932 x 956 = 325247719680
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
932 : 1, 2, 4, 233, 466, 932
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 468,780,932,956, is 4.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
780:2x 2x 3x 5x 13
932:2x 2x 233
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 3x 13 = 624
Therefore, the value for common factors is 624.
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 = 325247719680/(4x624)
LCM = 325247719680/2496
LCM = 130307580
Thus, we can understand that the LCM of 468,780,932,956 is 130307580.
