The LCM of 994,645,681,986,215 is 71749499430.
Find LCM of 994,645,681,986,215 with Prime Factorization
| 2 | 994, 645, 681, 986, 215 |
| 3 | 497, 645, 681, 493, 215 |
| 5 | 497, 215, 227, 493, 215 |
| 43 | 497, 43, 227, 493, 43 |
| 497, 1, 227, 493, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 497 x 1 x 227 x 493 x 1 = 71749499430
Therefore, the lowest common multiple of 994,645,681,986,215 is 71749499430.
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.
994 x 645 x 681 x 986 x 215 = 92556854264700
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
645 : 1, 3, 5, 15, 43, 129, 215, 645
681 : 1, 3, 227, 681
986 : 1, 2, 17, 29, 34, 58, 493, 986
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,645,681,986,215, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
645:3x 5x 43
681:3x 227
986:2x 17x 29
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 43 = 1290
Therefore, the value for common factors is 1290.
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 = 92556854264700/(1x1290)
LCM = 92556854264700/1290
LCM = 71749499430
Thus, we can understand that the LCM of 994,645,681,986,215 is 71749499430.
