Given numbers are 855,143,494,782,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,143,494,782,661 is 63199023030.
Find LCM of 855,143,494,782,661 with Prime Factorization
| 2 | 855, 143, 494, 782, 661 |
| 13 | 855, 143, 247, 391, 661 |
| 19 | 855, 11, 19, 391, 661 |
| 45, 11, 1, 391, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 45 x 11 x 1 x 391 x 661 = 63199023030
Therefore, the lowest common multiple of 855,143,494,782,661 is 63199023030.
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.
855 x 143 x 494 x 782 x 661 = 31220317376820
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
143 : 1, 11, 13, 143
494 : 1, 2, 13, 19, 26, 38, 247, 494
782 : 1, 2, 17, 23, 34, 46, 391, 782
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,143,494,782,661, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
143:11x 13
494:2x 13x 19
782:2x 17x 23
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 31220317376820/(1x494)
LCM = 31220317376820/494
LCM = 63199023030
Thus, we can understand that the LCM of 855,143,494,782,661 is 63199023030.
