Given numbers are 646,817,218,191
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,817,218,191 is 578310182.
Find LCM of 646,817,218,191 with Prime Factorization
2 | 646, 817, 218, 191 |
19 | 323, 817, 109, 191 |
17, 43, 109, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 17 x 43 x 109 x 191 = 578310182
Therefore, the lowest common multiple of 646,817,218,191 is 578310182.
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.
646 x 817 x 218 x 191 = 21975786916
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
817 : 1, 19, 43, 817
218 : 1, 2, 109, 218
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,817,218,191, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
817:19x 43
218:2x 109
191:191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 21975786916/(1x38)
LCM = 21975786916/38
LCM = 578310182
Thus, we can understand that the LCM of 646,817,218,191 is 578310182.
