Given numbers are 838,910,991,686,533
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,910,991,686,533 is 759117505510.
Find LCM of 838,910,991,686,533 with Prime Factorization
| 2 | 838, 910, 991, 686, 533 |
| 7 | 419, 455, 991, 343, 533 |
| 13 | 419, 65, 991, 49, 533 |
| 419, 5, 991, 49, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 419 x 5 x 991 x 49 x 41 = 759117505510
Therefore, the lowest common multiple of 838,910,991,686,533 is 759117505510.
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.
838 x 910 x 991 x 686 x 533 = 276318772005640
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.
838 : 1, 2, 419, 838
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
991 : 1, 991
686 : 1, 2, 7, 14, 49, 98, 343, 686
533 : 1, 13, 41, 533
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,910,991,686,533, is 1.
Now, the common factors can be found like this.
838:2x 419
910:2x 5x 7x 13
991:991
686:2x 7x 7x 7
533:13x 41
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 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 276318772005640/(1x364)
LCM = 276318772005640/364
LCM = 759117505510
Thus, we can understand that the LCM of 838,910,991,686,533 is 759117505510.
