Given numbers are 689,351,741,858,101
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,351,741,858,101 is 785381454.
Find LCM of 689,351,741,858,101 with Prime Factorization
| 3 | 689, 351, 741, 858, 101 |
| 13 | 689, 117, 247, 286, 101 |
| 53, 9, 19, 22, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 53 x 9 x 19 x 22 x 101 = 785381454
Therefore, the lowest common multiple of 689,351,741,858,101 is 785381454.
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.
689 x 351 x 741 x 858 x 101 = 15529347489942
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.
689 : 1, 13, 53, 689
351 : 1, 3, 9, 13, 27, 39, 117, 351
741 : 1, 3, 13, 19, 39, 57, 247, 741
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
101 : 1, 101
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,351,741,858,101, is 1.
Now, the common factors can be found like this.
689:13x 53
351:3x 3x 3x 13
741:3x 13x 19
858:2x 3x 11x 13
101:101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 13x 13 = 19773
Therefore, the value for common factors is 19773.
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 = 15529347489942/(1x19773)
LCM = 15529347489942/19773
LCM = 785381454
Thus, we can understand that the LCM of 689,351,741,858,101 is 785381454.
