Given numbers are 407,962,814,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,962,814,981 is 10380942.
Find LCM of 407,962,814,981 with Prime Factorization
| 2 | 407, 962, 814, 981 |
| 11 | 407, 481, 407, 981 |
| 37 | 37, 481, 37, 981 |
| 1, 13, 1, 981 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 1 x 13 x 1 x 981 = 10380942
Therefore, the lowest common multiple of 407,962,814,981 is 10380942.
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.
407 x 962 x 814 x 981 = 312653211156
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.
407 : 1, 11, 37, 407
962 : 1, 2, 13, 26, 37, 74, 481, 962
814 : 1, 2, 11, 22, 37, 74, 407, 814
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,962,814,981, is 1.
Now, the common factors can be found like this.
407:11x 37
962:2x 13x 37
814:2x 11x 37
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 37x 37 = 30118
Therefore, the value for common factors is 30118.
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 = 312653211156/(1x30118)
LCM = 312653211156/30118
LCM = 10380942
Thus, we can understand that the LCM of 407,962,814,981 is 10380942.
