Given numbers are 487,782,468,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,782,468,974 is 89115156.
Find LCM of 487,782,468,974 with Prime Factorization
| 2 | 487, 782, 468, 974 |
| 487 | 487, 391, 234, 487 |
| 1, 391, 234, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 487 x 1 x 391 x 234 x 1 = 89115156
Therefore, the lowest common multiple of 487,782,468,974 is 89115156.
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.
487 x 782 x 468 x 974 = 173596323888
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.
487 : 1, 487
782 : 1, 2, 17, 23, 34, 46, 391, 782
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,782,468,974, is 1.
Now, the common factors can be found like this.
487:487
782:2x 17x 23
468:2x 2x 3x 3x 13
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 487 = 1948
Therefore, the value for common factors is 1948.
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 = 173596323888/(1x1948)
LCM = 173596323888/1948
LCM = 89115156
Thus, we can understand that the LCM of 487,782,468,974 is 89115156.
