Given numbers are 836,276,316,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,276,316,981 is 1490150772.
Find LCM of 836,276,316,981 with Prime Factorization
| 2 | 836, 276, 316, 981 |
| 2 | 418, 138, 158, 981 |
| 3 | 209, 69, 79, 981 |
| 209, 23, 79, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 209 x 23 x 79 x 327 = 1490150772
Therefore, the lowest common multiple of 836,276,316,981 is 1490150772.
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 276 x 316 x 981 = 71527237056
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
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
316 : 1, 2, 4, 79, 158, 316
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,276,316,981, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
276:2x 2x 3x 23
316:2x 2x 79
981:3x 3x 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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 71527237056/(1x48)
LCM = 71527237056/48
LCM = 1490150772
Thus, we can understand that the LCM of 836,276,316,981 is 1490150772.
