Given numbers are 410,210,691,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 410,210,691,779 is 113040690.
Find LCM of 410,210,691,779 with Prime Factorization
| 2 | 410, 210, 691, 779 |
| 5 | 205, 105, 691, 779 |
| 41 | 41, 21, 691, 779 |
| 1, 21, 691, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 1 x 21 x 691 x 19 = 113040690
Therefore, the lowest common multiple of 410,210,691,779 is 113040690.
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.
410 x 210 x 691 x 779 = 46346682900
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.
410 : 1, 2, 5, 10, 41, 82, 205, 410
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
691 : 1, 691
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 410,210,691,779, is 1.
Now, the common factors can be found like this.
410:2x 5x 41
210:2x 3x 5x 7
691:691
779:19x 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 5x 41 = 410
Therefore, the value for common factors is 410.
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 = 46346682900/(1x410)
LCM = 46346682900/410
LCM = 113040690
Thus, we can understand that the LCM of 410,210,691,779 is 113040690.
