Given numbers are 726,407,835,121,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,407,835,121,842 is 9442933170.
Find LCM of 726,407,835,121,842 with Prime Factorization
2 | 726, 407, 835, 121, 842 |
11 | 363, 407, 835, 121, 421 |
11 | 33, 37, 835, 11, 421 |
3, 37, 835, 1, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 3 x 37 x 835 x 1 x 421 = 9442933170
Therefore, the lowest common multiple of 726,407,835,121,842 is 9442933170.
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.
726 x 407 x 835 x 121 x 842 = 25137088098540
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
407 : 1, 11, 37, 407
835 : 1, 5, 167, 835
121 : 1, 11, 121
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,407,835,121,842, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
407:11x 37
835:5x 167
121:11x 11
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 11 = 2662
Therefore, the value for common factors is 2662.
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 = 25137088098540/(1x2662)
LCM = 25137088098540/2662
LCM = 9442933170
Thus, we can understand that the LCM of 726,407,835,121,842 is 9442933170.
