Find LCM of 398,495,755,660,858 with Prime Factorization
| 2 | 398, 495, 755, 660, 858 |
| 3 | 199, 495, 755, 330, 429 |
| 5 | 199, 165, 755, 110, 143 |
| 11 | 199, 33, 151, 22, 143 |
| 199, 3, 151, 2, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 199 x 3 x 151 x 2 x 13 = 773461260
Therefore, the lowest common multiple of 398,495,755,660,858 is 773461260.
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.
398 x 495 x 755 x 660 x 858 = 84229931214000
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.
398 : 1, 2, 199, 398
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
755 : 1, 5, 151, 755
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,495,755,660,858, is 1.
Now, the common factors can be found like this.
398:2x 199
495:3x 3x 5x 11
755:5x 151
660:2x 2x 3x 5x 11
858:2x 3x 11x 13
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 3x 5x 5x 11x 11 = 108900
Therefore, the value for common factors is 108900.
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 = 84229931214000/(1x108900)
LCM = 84229931214000/108900
LCM = 773461260
Thus, we can understand that the LCM of 398,495,755,660,858 is 773461260.
