Given numbers are 285,835,813,931,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,835,813,931,488 is 308422834440.
Find LCM of 285,835,813,931,488 with Prime Factorization
3 | 285, 835, 813, 931, 488 |
5 | 95, 835, 271, 931, 488 |
19 | 19, 167, 271, 931, 488 |
1, 167, 271, 49, 488 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 1 x 167 x 271 x 49 x 488 = 308422834440
Therefore, the lowest common multiple of 285,835,813,931,488 is 308422834440.
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 835 x 813 x 931 x 488 = 87900507815400
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
835 : 1, 5, 167, 835
813 : 1, 3, 271, 813
931 : 1, 7, 19, 49, 133, 931
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,835,813,931,488, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
835:5x 167
813:3x 271
931:7x 7x 19
488:2x 2x 2x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19 = 285
Therefore, the value for common factors is 285.
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 = 87900507815400/(1x285)
LCM = 87900507815400/285
LCM = 308422834440
Thus, we can understand that the LCM of 285,835,813,931,488 is 308422834440.
