Given numbers are 129,389,666,555,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 129,389,666,555,481 is 724111830.
Find LCM of 129,389,666,555,481 with Prime Factorization
3 | 129, 389, 666, 555, 481 |
37 | 43, 389, 222, 185, 481 |
43, 389, 6, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 43 x 389 x 6 x 5 x 13 = 724111830
Therefore, the lowest common multiple of 129,389,666,555,481 is 724111830.
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.
129 x 389 x 666 x 555 x 481 = 8921781857430
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.
129 : 1, 3, 43, 129
389 : 1, 389
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
555 : 1, 3, 5, 15, 37, 111, 185, 555
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,389,666,555,481, is 1.
Now, the common factors can be found like this.
129:3x 43
389:389
666:2x 3x 3x 37
555:3x 5x 37
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 37x 37 = 12321
Therefore, the value for common factors is 12321.
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 = 8921781857430/(1x12321)
LCM = 8921781857430/12321
LCM = 724111830
Thus, we can understand that the LCM of 129,389,666,555,481 is 724111830.
