Given numbers are 445,640,424,935,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,640,424,935,392 is 27661997440.
Find LCM of 445,640,424,935,392 with Prime Factorization
| 2 | 445, 640, 424, 935, 392 |
| 2 | 445, 320, 212, 935, 196 |
| 2 | 445, 160, 106, 935, 98 |
| 5 | 445, 80, 53, 935, 49 |
| 89, 16, 53, 187, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 89 x 16 x 53 x 187 x 49 = 27661997440
Therefore, the lowest common multiple of 445,640,424,935,392 is 27661997440.
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 640 x 424 x 935 x 392 = 44259195904000
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
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
424 : 1, 2, 4, 8, 53, 106, 212, 424
935 : 1, 5, 11, 17, 55, 85, 187, 935
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,640,424,935,392, is 1.
Now, the common factors can be found like this.
445:5x 89
640:2x 2x 2x 2x 2x 2x 2x 5
424:2x 2x 2x 53
935:5x 11x 17
392:2x 2x 2x 7x 7
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 2x 2x 2x 2x 5x 5 = 1600
Therefore, the value for common factors is 1600.
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 = 44259195904000/(1x1600)
LCM = 44259195904000/1600
LCM = 27661997440
Thus, we can understand that the LCM of 445,640,424,935,392 is 27661997440.
