Given numbers are 343,221,890,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,221,890,666 is 22465735110.
Find LCM of 343,221,890,666 with Prime Factorization
| 2 | 343, 221, 890, 666 |
| 343, 221, 445, 333 |
Multiply the prime numbers at the bottom and the left side.
2 x 343 x 221 x 445 x 333 = 22465735110
Therefore, the lowest common multiple of 343,221,890,666 is 22465735110.
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.
343 x 221 x 890 x 666 = 44931470220
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.
343 : 1, 7, 49, 343
221 : 1, 13, 17, 221
890 : 1, 2, 5, 10, 89, 178, 445, 890
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,221,890,666, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
221:13x 17
890:2x 5x 89
666:2x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 44931470220/(1x2)
LCM = 44931470220/2
LCM = 22465735110
Thus, we can understand that the LCM of 343,221,890,666 is 22465735110.
