Given numbers are 621,495,120,398,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,495,120,398,911 is 49535406360.
Find LCM of 621,495,120,398,911 with Prime Factorization
| 2 | 621, 495, 120, 398, 911 |
| 3 | 621, 495, 60, 199, 911 |
| 3 | 207, 165, 20, 199, 911 |
| 5 | 69, 55, 20, 199, 911 |
| 69, 11, 4, 199, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 69 x 11 x 4 x 199 x 911 = 49535406360
Therefore, the lowest common multiple of 621,495,120,398,911 is 49535406360.
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.
621 x 495 x 120 x 398 x 911 = 13374559717200
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
398 : 1, 2, 199, 398
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,495,120,398,911, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
495:3x 3x 5x 11
120:2x 2x 2x 3x 5
398:2x 199
911:911
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 13374559717200/(1x270)
LCM = 13374559717200/270
LCM = 49535406360
Thus, we can understand that the LCM of 621,495,120,398,911 is 49535406360.
