Given numbers are 952,783,842,770,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 952,783,842,770,646 is 327942042120.
Find LCM of 952,783,842,770,646 with Prime Factorization
| 2 | 952, 783, 842, 770, 646 |
| 7 | 476, 783, 421, 385, 323 |
| 17 | 68, 783, 421, 55, 323 |
| 4, 783, 421, 55, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 4 x 783 x 421 x 55 x 19 = 327942042120
Therefore, the lowest common multiple of 952,783,842,770,646 is 327942042120.
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.
952 x 783 x 842 x 770 x 646 = 312200824098240
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.
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
783 : 1, 3, 9, 27, 29, 87, 261, 783
842 : 1, 2, 421, 842
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 952,783,842,770,646, is 1.
Now, the common factors can be found like this.
952:2x 2x 2x 7x 17
783:3x 3x 3x 29
842:2x 421
770:2x 5x 7x 11
646:2x 17x 19
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 7x 17 = 952
Therefore, the value for common factors is 952.
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 = 312200824098240/(1x952)
LCM = 312200824098240/952
LCM = 327942042120
Thus, we can understand that the LCM of 952,783,842,770,646 is 327942042120.
