The LCM of 431,644,875,362,905 is 6279885500.
Find LCM of 431,644,875,362,905 with Prime Factorization
| 2 | 431, 644, 875, 362, 905 |
| 5 | 431, 322, 875, 181, 905 |
| 7 | 431, 322, 175, 181, 181 |
| 181 | 431, 46, 25, 181, 181 |
| 431, 46, 25, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 181 x 431 x 46 x 25 x 1 x 1 = 6279885500
Therefore, the lowest common multiple of 431,644,875,362,905 is 6279885500.
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 644 x 875 x 362 x 905 = 79566149285000
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
875 : 1, 5, 7, 25, 35, 125, 175, 875
362 : 1, 2, 181, 362
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,644,875,362,905, is 1.
Now, the common factors can be found like this.
431:431
644:2x 2x 7x 23
875:5x 5x 5x 7
362:2x 181
905:5x 181
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 7x 181 = 12670
Therefore, the value for common factors is 12670.
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 = 79566149285000/(1x12670)
LCM = 79566149285000/12670
LCM = 6279885500
Thus, we can understand that the LCM of 431,644,875,362,905 is 6279885500.
