Given numbers are 421,686,726,529,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,686,726,529,923 is 51188241430326.
Find LCM of 421,686,726,529,923 with Prime Factorization
| 2 | 421, 686, 726, 529, 923 |
| 421, 343, 363, 529, 923 |
Multiply the prime numbers at the bottom and the left side.
2 x 421 x 343 x 363 x 529 x 923 = 51188241430326
Therefore, the lowest common multiple of 421,686,726,529,923 is 51188241430326.
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.
421 x 686 x 726 x 529 x 923 = 102376482860652
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.
421 : 1, 421
686 : 1, 2, 7, 14, 49, 98, 343, 686
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
529 : 1, 23, 529
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,686,726,529,923, is 1.
Now, the common factors can be found like this.
421:421
686:2x 7x 7x 7
726:2x 3x 11x 11
529:23x 23
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 102376482860652/(1x2)
LCM = 102376482860652/2
LCM = 51188241430326
Thus, we can understand that the LCM of 421,686,726,529,923 is 51188241430326.
