Find LCM of 816,836,865,210,889 with Prime Factorization
2 | 816, 836, 865, 210, 889 |
2 | 408, 418, 865, 105, 889 |
3 | 204, 209, 865, 105, 889 |
5 | 68, 209, 865, 35, 889 |
7 | 68, 209, 173, 7, 889 |
68, 209, 173, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 68 x 209 x 173 x 1 x 127 = 131145777840
Therefore, the lowest common multiple of 816,836,865,210,889 is 131145777840.
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.
816 x 836 x 865 x 210 x 889 = 110162453385600
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
865 : 1, 5, 173, 865
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,836,865,210,889, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
836:2x 2x 11x 19
865:5x 173
210:2x 3x 5x 7
889:7x 127
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 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 110162453385600/(1x840)
LCM = 110162453385600/840
LCM = 131145777840
Thus, we can understand that the LCM of 816,836,865,210,889 is 131145777840.
