Find LCM of 122,917,310,819,665 with Prime Factorization
2 | 122, 917, 310, 819, 665 |
5 | 61, 917, 155, 819, 665 |
7 | 61, 917, 31, 819, 133 |
61, 131, 31, 117, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 61 x 131 x 31 x 117 x 19 = 38547864810
Therefore, the lowest common multiple of 122,917,310,819,665 is 38547864810.
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.
122 x 917 x 310 x 819 x 665 = 18888453756900
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.
122 : 1, 2, 61, 122
917 : 1, 7, 131, 917
310 : 1, 2, 5, 10, 31, 62, 155, 310
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,917,310,819,665, is 1.
Now, the common factors can be found like this.
122:2x 61
917:7x 131
310:2x 5x 31
819:3x 3x 7x 13
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 18888453756900/(1x490)
LCM = 18888453756900/490
LCM = 38547864810
Thus, we can understand that the LCM of 122,917,310,819,665 is 38547864810.
