Given numbers are 398,941,632,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,941,632,724 is 21420931528.
Find LCM of 398,941,632,724 with Prime Factorization
| 2 | 398, 941, 632, 724 |
| 2 | 199, 941, 316, 362 |
| 199, 941, 158, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 199 x 941 x 158 x 181 = 21420931528
Therefore, the lowest common multiple of 398,941,632,724 is 21420931528.
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 941 x 632 x 724 = 171367452224
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
941 : 1, 941
632 : 1, 2, 4, 8, 79, 158, 316, 632
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,941,632,724, is 1.
Now, the common factors can be found like this.
398:2x 199
941:941
632:2x 2x 2x 79
724:2x 2x 181
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 2 = 8
Therefore, the value for common factors is 8.
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 = 171367452224/(1x8)
LCM = 171367452224/8
LCM = 21420931528
Thus, we can understand that the LCM of 398,941,632,724 is 21420931528.
