Given numbers are 836,865,779,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,865,779,979 is 2638737860.
Find LCM of 836,865,779,979 with Prime Factorization
| 11 | 836, 865, 779, 979 |
| 19 | 76, 865, 779, 89 |
| 4, 865, 41, 89 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 4 x 865 x 41 x 89 = 2638737860
Therefore, the lowest common multiple of 836,865,779,979 is 2638737860.
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.
836 x 865 x 779 x 979 = 551496212740
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
865 : 1, 5, 173, 865
779 : 1, 19, 41, 779
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,865,779,979, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
865:5x 173
779:19x 41
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 551496212740/(1x209)
LCM = 551496212740/209
LCM = 2638737860
Thus, we can understand that the LCM of 836,865,779,979 is 2638737860.
