Given numbers are 982,814,721,491,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 982,814,721,491,756 is 15560907516.
Find LCM of 982,814,721,491,756 with Prime Factorization
| 2 | 982, 814, 721, 491, 756 |
| 7 | 491, 407, 721, 491, 378 |
| 491 | 491, 407, 103, 491, 54 |
| 1, 407, 103, 1, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 491 x 1 x 407 x 103 x 1 x 54 = 15560907516
Therefore, the lowest common multiple of 982,814,721,491,756 is 15560907516.
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.
982 x 814 x 721 x 491 x 756 = 213931356529968
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.
982 : 1, 2, 491, 982
814 : 1, 2, 11, 22, 37, 74, 407, 814
721 : 1, 7, 103, 721
491 : 1, 491
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 982,814,721,491,756, is 1.
Now, the common factors can be found like this.
982:2x 491
814:2x 11x 37
721:7x 103
491:491
756:2x 2x 3x 3x 3x 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 2x 7x 491 = 13748
Therefore, the value for common factors is 13748.
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 = 213931356529968/(1x13748)
LCM = 213931356529968/13748
LCM = 15560907516
Thus, we can understand that the LCM of 982,814,721,491,756 is 15560907516.
