Find LCM of 838,931,732,609,290 with Prime Factorization
| 2 | 838, 931, 732, 609, 290 |
| 3 | 419, 931, 366, 609, 145 |
| 7 | 419, 931, 122, 203, 145 |
| 29 | 419, 133, 122, 29, 145 |
| 419, 133, 122, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 419 x 133 x 122 x 1 x 5 = 41404046460
Therefore, the lowest common multiple of 838,931,732,609,290 is 41404046460.
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.
838 x 931 x 732 x 609 x 290 = 100860257176560
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.
838 : 1, 2, 419, 838
931 : 1, 7, 19, 49, 133, 931
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
609 : 1, 3, 7, 21, 29, 87, 203, 609
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,931,732,609,290, is 1.
Now, the common factors can be found like this.
838:2x 419
931:7x 7x 19
732:2x 2x 3x 61
609:3x 7x 29
290:2x 5x 29
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 3x 7x 29 = 2436
Therefore, the value for common factors is 2436.
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 = 100860257176560/(1x2436)
LCM = 100860257176560/2436
LCM = 41404046460
Thus, we can understand that the LCM of 838,931,732,609,290 is 41404046460.
