Given numbers are 942,646,323,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,646,323,703 is 11257842.
Find LCM of 942,646,323,703 with Prime Factorization
| 2 | 942, 646, 323, 703 |
| 17 | 471, 323, 323, 703 |
| 19 | 471, 19, 19, 703 |
| 471, 1, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 471 x 1 x 1 x 37 = 11257842
Therefore, the lowest common multiple of 942,646,323,703 is 11257842.
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.
942 x 646 x 323 x 703 = 138178752708
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
646 : 1, 2, 17, 19, 34, 38, 323, 646
323 : 1, 17, 19, 323
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,646,323,703, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
646:2x 17x 19
323:17x 19
703:19x 37
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 19x 19 = 12274
Therefore, the value for common factors is 12274.
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 = 138178752708/(1x12274)
LCM = 138178752708/12274
LCM = 11257842
Thus, we can understand that the LCM of 942,646,323,703 is 11257842.
