Given numbers are 346,643,707,456,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 346,643,707,456,646 is 609663582696.
Find LCM of 346,643,707,456,646 with Prime Factorization
| 2 | 346, 643, 707, 456, 646 |
| 19 | 173, 643, 707, 228, 323 |
| 173, 643, 707, 12, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 173 x 643 x 707 x 12 x 17 = 609663582696
Therefore, the lowest common multiple of 346,643,707,456,646 is 609663582696.
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.
346 x 643 x 707 x 456 x 646 = 46334432284896
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.
346 : 1, 2, 173, 346
643 : 1, 643
707 : 1, 7, 101, 707
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
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 346,643,707,456,646, is 1.
Now, the common factors can be found like this.
346:2x 173
643:643
707:7x 101
456:2x 2x 2x 3x 19
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 19 = 76
Therefore, the value for common factors is 76.
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 = 46334432284896/(1x76)
LCM = 46334432284896/76
LCM = 609663582696
Thus, we can understand that the LCM of 346,643,707,456,646 is 609663582696.
