Given numbers are 784,726,457,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,726,457,913 is 10794859152.
Find LCM of 784,726,457,913 with Prime Factorization
| 2 | 784, 726, 457, 913 |
| 11 | 392, 363, 457, 913 |
| 392, 33, 457, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 392 x 33 x 457 x 83 = 10794859152
Therefore, the lowest common multiple of 784,726,457,913 is 10794859152.
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.
784 x 726 x 457 x 913 = 237486901344
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
457 : 1, 457
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,726,457,913, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
726:2x 3x 11x 11
457:457
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 237486901344/(1x22)
LCM = 237486901344/22
LCM = 10794859152
Thus, we can understand that the LCM of 784,726,457,913 is 10794859152.
