Given numbers are 409,550,385,727,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,550,385,727,749 is 122490448850.
Find LCM of 409,550,385,727,749 with Prime Factorization
5 | 409, 550, 385, 727, 749 |
7 | 409, 110, 77, 727, 749 |
11 | 409, 110, 11, 727, 107 |
409, 10, 1, 727, 107 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 409 x 10 x 1 x 727 x 107 = 122490448850
Therefore, the lowest common multiple of 409,550,385,727,749 is 122490448850.
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.
409 x 550 x 385 x 727 x 749 = 47158822807250
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.
409 : 1, 409
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
385 : 1, 5, 7, 11, 35, 55, 77, 385
727 : 1, 727
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,550,385,727,749, is 1.
Now, the common factors can be found like this.
409:409
550:2x 5x 5x 11
385:5x 7x 11
727:727
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11 = 385
Therefore, the value for common factors is 385.
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 = 47158822807250/(1x385)
LCM = 47158822807250/385
LCM = 122490448850
Thus, we can understand that the LCM of 409,550,385,727,749 is 122490448850.
