Given numbers are 842,740,884,884
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,740,884,884 is 68850340.
Find LCM of 842,740,884,884 with Prime Factorization
| 2 | 842, 740, 884, 884 |
| 2 | 421, 370, 442, 442 |
| 13 | 421, 185, 221, 221 |
| 17 | 421, 185, 17, 17 |
| 421, 185, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 421 x 185 x 1 x 1 = 68850340
Therefore, the lowest common multiple of 842,740,884,884 is 68850340.
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.
842 x 740 x 884 x 884 = 486909604480
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.
842 : 1, 2, 421, 842
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,740,884,884, is 2.
Now, the common factors can be found like this.
842:2x 421
740:2x 2x 5x 37
884:2x 2x 13x 17
884:2x 2x 13x 17
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 13x 17 = 3536
Therefore, the value for common factors is 3536.
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 = 486909604480/(2x3536)
LCM = 486909604480/7072
LCM = 68850340
Thus, we can understand that the LCM of 842,740,884,884 is 68850340.
