Given numbers are 445,370,614,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,370,614,921 is 30328530.
Find LCM of 445,370,614,921 with Prime Factorization
| 2 | 445, 370, 614, 921 |
| 5 | 445, 185, 307, 921 |
| 307 | 89, 37, 307, 921 |
| 89, 37, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 307 x 89 x 37 x 1 x 3 = 30328530
Therefore, the lowest common multiple of 445,370,614,921 is 30328530.
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.
445 x 370 x 614 x 921 = 93108587100
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.
445 : 1, 5, 89, 445
370 : 1, 2, 5, 10, 37, 74, 185, 370
614 : 1, 2, 307, 614
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,370,614,921, is 1.
Now, the common factors can be found like this.
445:5x 89
370:2x 5x 37
614:2x 307
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 307 = 3070
Therefore, the value for common factors is 3070.
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 = 93108587100/(1x3070)
LCM = 93108587100/3070
LCM = 30328530
Thus, we can understand that the LCM of 445,370,614,921 is 30328530.
