The LCM of 299,253,138,821,741 is 307830666.
Find LCM of 299,253,138,821,741 with Prime Factorization
| 3 | 299, 253, 138, 821, 741 |
| 13 | 299, 253, 46, 821, 247 |
| 23 | 23, 253, 46, 821, 19 |
| 1, 11, 2, 821, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 1 x 11 x 2 x 821 x 19 = 307830666
Therefore, the lowest common multiple of 299,253,138,821,741 is 307830666.
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.
299 x 253 x 138 x 821 x 741 = 6350854470246
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.
299 : 1, 13, 23, 299
253 : 1, 11, 23, 253
138 : 1, 2, 3, 6, 23, 46, 69, 138
821 : 1, 821
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,253,138,821,741, is 1.
Now, the common factors can be found like this.
299:13x 23
253:11x 23
138:2x 3x 23
821:821
741:3x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 23x 23 = 20631
Therefore, the value for common factors is 20631.
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 = 6350854470246/(1x20631)
LCM = 6350854470246/20631
LCM = 307830666
Thus, we can understand that the LCM of 299,253,138,821,741 is 307830666.
