Given numbers are 445,315,627,749,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,315,627,749,920 is 115358193720.
Find LCM of 445,315,627,749,920 with Prime Factorization
| 3 | 445, 315, 627, 749, 920 |
| 5 | 445, 105, 209, 749, 920 |
| 7 | 89, 21, 209, 749, 184 |
| 89, 3, 209, 107, 184 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 89 x 3 x 209 x 107 x 184 = 115358193720
Therefore, the lowest common multiple of 445,315,627,749,920 is 115358193720.
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 315 x 627 x 749 x 920 = 60563051703000
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
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
627 : 1, 3, 11, 19, 33, 57, 209, 627
749 : 1, 7, 107, 749
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,315,627,749,920, is 1.
Now, the common factors can be found like this.
445:5x 89
315:3x 3x 5x 7
627:3x 11x 19
749:7x 107
920:2x 2x 2x 5x 23
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 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 60563051703000/(1x525)
LCM = 60563051703000/525
LCM = 115358193720
Thus, we can understand that the LCM of 445,315,627,749,920 is 115358193720.
