Given numbers are 377,638,686,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,638,686,869 is 224742518.
Find LCM of 377,638,686,869 with Prime Factorization
| 2 | 377, 638, 686, 869 |
| 11 | 377, 319, 343, 869 |
| 29 | 377, 29, 343, 79 |
| 13, 1, 343, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 13 x 1 x 343 x 79 = 224742518
Therefore, the lowest common multiple of 377,638,686,869 is 224742518.
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.
377 x 638 x 686 x 869 = 143385726484
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.
377 : 1, 13, 29, 377
638 : 1, 2, 11, 22, 29, 58, 319, 638
686 : 1, 2, 7, 14, 49, 98, 343, 686
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,638,686,869, is 1.
Now, the common factors can be found like this.
377:13x 29
638:2x 11x 29
686:2x 7x 7x 7
869:11x 79
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 29 = 638
Therefore, the value for common factors is 638.
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 = 143385726484/(1x638)
LCM = 143385726484/638
LCM = 224742518
Thus, we can understand that the LCM of 377,638,686,869 is 224742518.
