Find LCM of 851,213,667,771,994 with Prime Factorization
| 3 | 851, 213, 667, 771, 994 |
| 23 | 851, 71, 667, 257, 994 |
| 71 | 37, 71, 29, 257, 994 |
| 37, 1, 29, 257, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 71 x 37 x 1 x 29 x 257 x 14 = 18913343946
Therefore, the lowest common multiple of 851,213,667,771,994 is 18913343946.
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.
851 x 213 x 667 x 771 x 994 = 92656471991454
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.
851 : 1, 23, 37, 851
213 : 1, 3, 71, 213
667 : 1, 23, 29, 667
771 : 1, 3, 257, 771
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,213,667,771,994, is 1.
Now, the common factors can be found like this.
851:23x 37
213:3x 71
667:23x 29
771:3x 257
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23x 71 = 4899
Therefore, the value for common factors is 4899.
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 = 92656471991454/(1x4899)
LCM = 92656471991454/4899
LCM = 18913343946
Thus, we can understand that the LCM of 851,213,667,771,994 is 18913343946.
