Given numbers are 392,982,714,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,982,714,793 is 7784145096.
Find LCM of 392,982,714,793 with Prime Factorization
| 2 | 392, 982, 714, 793 |
| 7 | 196, 491, 357, 793 |
| 28, 491, 51, 793 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 28 x 491 x 51 x 793 = 7784145096
Therefore, the lowest common multiple of 392,982,714,793 is 7784145096.
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.
392 x 982 x 714 x 793 = 217956062688
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
982 : 1, 2, 491, 982
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,982,714,793, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
982:2x 491
714:2x 3x 7x 17
793:13x 61
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 7 = 28
Therefore, the value for common factors is 28.
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 = 217956062688/(1x28)
LCM = 217956062688/28
LCM = 7784145096
Thus, we can understand that the LCM of 392,982,714,793 is 7784145096.
