Given numbers are 398,870,464,464
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,870,464,464 is 1385040.
Find LCM of 398,870,464,464 with Prime Factorization
| 2 | 398, 870, 464, 464 |
| 2 | 199, 435, 232, 232 |
| 2 | 199, 435, 116, 116 |
| 2 | 199, 435, 58, 58 |
| 29 | 199, 435, 29, 29 |
| 199, 15, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 29 x 199 x 15 x 1 x 1 = 1385040
Therefore, the lowest common multiple of 398,870,464,464 is 1385040.
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 870 x 464 x 464 = 74548392960
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
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,870,464,464, is 2.
Now, the common factors can be found like this.
398:2x 199
870:2x 3x 5x 29
464:2x 2x 2x 2x 29
464:2x 2x 2x 2x 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 2x 2x 2x 29x 29 = 26912
Therefore, the value for common factors is 26912.
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 = 74548392960/(2x26912)
LCM = 74548392960/53824
LCM = 1385040
Thus, we can understand that the LCM of 398,870,464,464 is 1385040.
