Given numbers are 407,338,847,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,338,847,793 is 646147502.
Find LCM of 407,338,847,793 with Prime Factorization
| 11 | 407, 338, 847, 793 |
| 13 | 37, 338, 77, 793 |
| 37, 26, 77, 61 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 37 x 26 x 77 x 61 = 646147502
Therefore, the lowest common multiple of 407,338,847,793 is 646147502.
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 338 x 847 x 793 = 92399092786
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
338 : 1, 2, 13, 26, 169, 338
847 : 1, 7, 11, 77, 121, 847
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,338,847,793, is 1.
Now, the common factors can be found like this.
407:11x 37
338:2x 13x 13
847:7x 11x 11
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.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 92399092786/(1x143)
LCM = 92399092786/143
LCM = 646147502
Thus, we can understand that the LCM of 407,338,847,793 is 646147502.
