The LCM of 836,893,942,984 is 1517535624.
Find LCM of 836,893,942,984 with Prime Factorization
| 2 | 836, 893, 942, 984 |
| 2 | 418, 893, 471, 492 |
| 3 | 209, 893, 471, 246 |
| 19 | 209, 893, 157, 82 |
| 11, 47, 157, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 11 x 47 x 157 x 82 = 1517535624
Therefore, the lowest common multiple of 836,893,942,984 is 1517535624.
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 893 x 942 x 984 = 691996244544
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
893 : 1, 19, 47, 893
942 : 1, 2, 3, 6, 157, 314, 471, 942
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,893,942,984, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
893:19x 47
942:2x 3x 157
984:2x 2x 2x 3x 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 2x 2x 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 691996244544/(1x456)
LCM = 691996244544/456
LCM = 1517535624
Thus, we can understand that the LCM of 836,893,942,984 is 1517535624.
