The LCM of 652,805,399,989,434 is 39879387660.
Find LCM of 652,805,399,989,434 with Prime Factorization
| 2 | 652, 805, 399, 989, 434 |
| 7 | 326, 805, 399, 989, 217 |
| 23 | 326, 115, 57, 989, 31 |
| 326, 5, 57, 43, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 326 x 5 x 57 x 43 x 31 = 39879387660
Therefore, the lowest common multiple of 652,805,399,989,434 is 39879387660.
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.
652 x 805 x 399 x 989 x 434 = 89888139785640
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.
652 : 1, 2, 4, 163, 326, 652
805 : 1, 5, 7, 23, 35, 115, 161, 805
399 : 1, 3, 7, 19, 21, 57, 133, 399
989 : 1, 23, 43, 989
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,805,399,989,434, is 1.
Now, the common factors can be found like this.
652:2x 2x 163
805:5x 7x 23
399:3x 7x 19
989:23x 43
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 23 = 2254
Therefore, the value for common factors is 2254.
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 = 89888139785640/(1x2254)
LCM = 89888139785640/2254
LCM = 39879387660
Thus, we can understand that the LCM of 652,805,399,989,434 is 39879387660.
