Given numbers are 354,668,120,940,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,668,120,940,842 is 23395357320.
Find LCM of 354,668,120,940,842 with Prime Factorization
| 2 | 354, 668, 120, 940, 842 |
| 2 | 177, 334, 60, 470, 421 |
| 3 | 177, 167, 30, 235, 421 |
| 5 | 59, 167, 10, 235, 421 |
| 59, 167, 2, 47, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 167 x 2 x 47 x 421 = 23395357320
Therefore, the lowest common multiple of 354,668,120,940,842 is 23395357320.
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.
354 x 668 x 120 x 940 x 842 = 22459543027200
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
668 : 1, 2, 4, 167, 334, 668
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
842 : 1, 2, 421, 842
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,668,120,940,842, is 2.
Now, the common factors can be found like this.
354:2x 3x 59
668:2x 2x 167
120:2x 2x 2x 3x 5
940:2x 2x 5x 47
842:2x 421
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 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 22459543027200/(2x480)
LCM = 22459543027200/960
LCM = 23395357320
Thus, we can understand that the LCM of 354,668,120,940,842 is 23395357320.
