Given numbers are 398,105,435,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,105,435,365 is 88469430.
Find LCM of 398,105,435,365 with Prime Factorization
| 3 | 398, 105, 435, 365 |
| 5 | 398, 35, 145, 365 |
| 398, 7, 29, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 398 x 7 x 29 x 73 = 88469430
Therefore, the lowest common multiple of 398,105,435,365 is 88469430.
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 105 x 435 x 365 = 6635207250
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
105 : 1, 3, 5, 7, 15, 21, 35, 105
435 : 1, 3, 5, 15, 29, 87, 145, 435
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,105,435,365, is 1.
Now, the common factors can be found like this.
398:2x 199
105:3x 5x 7
435:3x 5x 29
365:5x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5 = 75
Therefore, the value for common factors is 75.
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 = 6635207250/(1x75)
LCM = 6635207250/75
LCM = 88469430
Thus, we can understand that the LCM of 398,105,435,365 is 88469430.
