Given numbers are 913,862,688,455,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,862,688,455,431 is 123182179120.
Find LCM of 913,862,688,455,431 with Prime Factorization
| 2 | 913, 862, 688, 455, 431 |
| 431 | 913, 431, 344, 455, 431 |
| 913, 1, 344, 455, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 913 x 1 x 344 x 455 x 1 = 123182179120
Therefore, the lowest common multiple of 913,862,688,455,431 is 123182179120.
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.
913 x 862 x 688 x 455 x 431 = 106183038401440
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.
913 : 1, 11, 83, 913
862 : 1, 2, 431, 862
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
455 : 1, 5, 7, 13, 35, 65, 91, 455
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,862,688,455,431, is 1.
Now, the common factors can be found like this.
913:11x 83
862:2x 431
688:2x 2x 2x 2x 43
455:5x 7x 13
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 106183038401440/(1x862)
LCM = 106183038401440/862
LCM = 123182179120
Thus, we can understand that the LCM of 913,862,688,455,431 is 123182179120.
