Given numbers are 431,749,808,363,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,749,808,363,764 is 18084663859416.
Find LCM of 431,749,808,363,764 with Prime Factorization
| 2 | 431, 749, 808, 363, 764 |
| 2 | 431, 749, 404, 363, 382 |
| 431, 749, 202, 363, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 431 x 749 x 202 x 363 x 191 = 18084663859416
Therefore, the lowest common multiple of 431,749,808,363,764 is 18084663859416.
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.
431 x 749 x 808 x 363 x 764 = 72338655437664
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.
431 : 1, 431
749 : 1, 7, 107, 749
808 : 1, 2, 4, 8, 101, 202, 404, 808
363 : 1, 3, 11, 33, 121, 363
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,749,808,363,764, is 1.
Now, the common factors can be found like this.
431:431
749:7x 107
808:2x 2x 2x 101
363:3x 11x 11
764:2x 2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 72338655437664/(1x4)
LCM = 72338655437664/4
LCM = 18084663859416
Thus, we can understand that the LCM of 431,749,808,363,764 is 18084663859416.
