Given numbers are 285,501,741,748,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,501,741,748,637 is 22677875220.
Find LCM of 285,501,741,748,637 with Prime Factorization
| 3 | 285, 501, 741, 748, 637 |
| 13 | 95, 167, 247, 748, 637 |
| 19 | 95, 167, 19, 748, 49 |
| 5, 167, 1, 748, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 5 x 167 x 1 x 748 x 49 = 22677875220
Therefore, the lowest common multiple of 285,501,741,748,637 is 22677875220.
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.
285 x 501 x 741 x 748 x 637 = 50412916614060
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
501 : 1, 3, 167, 501
741 : 1, 3, 13, 19, 39, 57, 247, 741
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,501,741,748,637, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
501:3x 167
741:3x 13x 19
748:2x 2x 11x 17
637:7x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 19 = 2223
Therefore, the value for common factors is 2223.
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 = 50412916614060/(1x2223)
LCM = 50412916614060/2223
LCM = 22677875220
Thus, we can understand that the LCM of 285,501,741,748,637 is 22677875220.
