Given numbers are 343,142,666,765,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,142,666,765,546 is 17922103290.
Find LCM of 343,142,666,765,546 with Prime Factorization
| 2 | 343, 142, 666, 765, 546 |
| 3 | 343, 71, 333, 765, 273 |
| 3 | 343, 71, 111, 255, 91 |
| 7 | 343, 71, 37, 85, 91 |
| 49, 71, 37, 85, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 49 x 71 x 37 x 85 x 13 = 17922103290
Therefore, the lowest common multiple of 343,142,666,765,546 is 17922103290.
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 142 x 666 x 765 x 546 = 13549110087240
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
142 : 1, 2, 71, 142
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,142,666,765,546, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
142:2x 71
666:2x 3x 3x 37
765:3x 3x 5x 17
546:2x 3x 7x 13
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 13549110087240/(1x756)
LCM = 13549110087240/756
LCM = 17922103290
Thus, we can understand that the LCM of 343,142,666,765,546 is 17922103290.
