Given numbers are 398,109,750,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,109,750,635 is 2066067750.
Find LCM of 398,109,750,635 with Prime Factorization
| 2 | 398, 109, 750, 635 |
| 5 | 199, 109, 375, 635 |
| 199, 109, 75, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 199 x 109 x 75 x 127 = 2066067750
Therefore, the lowest common multiple of 398,109,750,635 is 2066067750.
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 109 x 750 x 635 = 20660677500
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
109 : 1, 109
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,109,750,635, is 1.
Now, the common factors can be found like this.
398:2x 199
109:109
750:2x 3x 5x 5x 5
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 20660677500/(1x10)
LCM = 20660677500/10
LCM = 2066067750
Thus, we can understand that the LCM of 398,109,750,635 is 2066067750.
