Given numbers are 154,858,109,338,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,858,109,338,388 is 1651037388.
Find LCM of 154,858,109,338,388 with Prime Factorization
2 | 154, 858, 109, 338, 388 |
11 | 77, 429, 109, 169, 194 |
13 | 7, 39, 109, 169, 194 |
7, 3, 109, 13, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 7 x 3 x 109 x 13 x 194 = 1651037388
Therefore, the lowest common multiple of 154,858,109,338,388 is 1651037388.
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.
154 x 858 x 109 x 338 x 388 = 1888786771872
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
109 : 1, 109
338 : 1, 2, 13, 26, 169, 338
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,858,109,338,388, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
858:2x 3x 11x 13
109:109
338:2x 13x 13
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 1888786771872/(1x1144)
LCM = 1888786771872/1144
LCM = 1651037388
Thus, we can understand that the LCM of 154,858,109,338,388 is 1651037388.
