Given numbers are 491,817,722,109,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,817,722,109,139 is 230955571486.
Find LCM of 491,817,722,109,139 with Prime Factorization
| 19 | 491, 817, 722, 109, 139 |
| 491, 43, 38, 109, 139 |
Multiply the prime numbers at the bottom and the left side.
19 x 491 x 43 x 38 x 109 x 139 = 230955571486
Therefore, the lowest common multiple of 491,817,722,109,139 is 230955571486.
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.
491 x 817 x 722 x 109 x 139 = 4388155858234
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.
491 : 1, 491
817 : 1, 19, 43, 817
722 : 1, 2, 19, 38, 361, 722
109 : 1, 109
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,817,722,109,139, is 1.
Now, the common factors can be found like this.
491:491
817:19x 43
722:2x 19x 19
109:109
139:139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 4388155858234/(1x19)
LCM = 4388155858234/19
LCM = 230955571486
Thus, we can understand that the LCM of 491,817,722,109,139 is 230955571486.
