Given numbers are 905,550,442,980,112
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,550,442,980,112 is 8624215600.
Find LCM of 905,550,442,980,112 with Prime Factorization
| 2 | 905, 550, 442, 980, 112 |
| 2 | 905, 275, 221, 490, 56 |
| 5 | 905, 275, 221, 245, 28 |
| 7 | 181, 55, 221, 49, 28 |
| 181, 55, 221, 7, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 181 x 55 x 221 x 7 x 4 = 8624215600
Therefore, the lowest common multiple of 905,550,442,980,112 is 8624215600.
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.
905 x 550 x 442 x 980 x 112 = 24147803680000
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.
905 : 1, 5, 181, 905
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
442 : 1, 2, 13, 17, 26, 34, 221, 442
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,550,442,980,112, is 1.
Now, the common factors can be found like this.
905:5x 181
550:2x 5x 5x 11
442:2x 13x 17
980:2x 2x 5x 7x 7
112:2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 5x 7 = 2800
Therefore, the value for common factors is 2800.
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 = 24147803680000/(1x2800)
LCM = 24147803680000/2800
LCM = 8624215600
Thus, we can understand that the LCM of 905,550,442,980,112 is 8624215600.
