Given numbers are 779,860,836,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,860,836,109 is 803258060.
Find LCM of 779,860,836,109 with Prime Factorization
| 2 | 779, 860, 836, 109 |
| 2 | 779, 430, 418, 109 |
| 19 | 779, 215, 209, 109 |
| 41, 215, 11, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 41 x 215 x 11 x 109 = 803258060
Therefore, the lowest common multiple of 779,860,836,109 is 803258060.
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.
779 x 860 x 836 x 109 = 61047612560
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.
779 : 1, 19, 41, 779
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,860,836,109, is 1.
Now, the common factors can be found like this.
779:19x 41
860:2x 2x 5x 43
836:2x 2x 11x 19
109:109
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 19 = 76
Therefore, the value for common factors is 76.
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 = 61047612560/(1x76)
LCM = 61047612560/76
LCM = 803258060
Thus, we can understand that the LCM of 779,860,836,109 is 803258060.
