Given numbers are 830,893,637,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,893,637,490 is 472138030.
Find LCM of 830,893,637,490 with Prime Factorization
| 2 | 830, 893, 637, 490 |
| 5 | 415, 893, 637, 245 |
| 7 | 83, 893, 637, 49 |
| 7 | 83, 893, 91, 7 |
| 83, 893, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 83 x 893 x 13 x 1 = 472138030
Therefore, the lowest common multiple of 830,893,637,490 is 472138030.
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.
830 x 893 x 637 x 490 = 231347634700
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
893 : 1, 19, 47, 893
637 : 1, 7, 13, 49, 91, 637
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,893,637,490, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
893:19x 47
637:7x 7x 13
490:2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 231347634700/(1x490)
LCM = 231347634700/490
LCM = 472138030
Thus, we can understand that the LCM of 830,893,637,490 is 472138030.
