Find LCM of 400,856,391,623,917 with Prime Factorization
2 | 400, 856, 391, 623, 917 |
2 | 200, 428, 391, 623, 917 |
2 | 100, 214, 391, 623, 917 |
7 | 50, 107, 391, 623, 917 |
50, 107, 391, 89, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 50 x 107 x 391 x 89 x 131 = 1365777232400
Therefore, the lowest common multiple of 400,856,391,623,917 is 1365777232400.
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.
400 x 856 x 391 x 623 x 917 = 76483525014400
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
856 : 1, 2, 4, 8, 107, 214, 428, 856
391 : 1, 17, 23, 391
623 : 1, 7, 89, 623
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,856,391,623,917, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
856:2x 2x 2x 107
391:17x 23
623:7x 89
917:7x 131
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 7 = 56
Therefore, the value for common factors is 56.
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 = 76483525014400/(1x56)
LCM = 76483525014400/56
LCM = 1365777232400
Thus, we can understand that the LCM of 400,856,391,623,917 is 1365777232400.
