Find LCM of 471,715,988,490,921 with Prime Factorization
| 2 | 471, 715, 988, 490, 921 |
| 3 | 471, 715, 494, 245, 921 |
| 5 | 157, 715, 494, 245, 307 |
| 13 | 157, 143, 494, 49, 307 |
| 157, 11, 38, 49, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 157 x 11 x 38 x 49 x 307 = 385012648020
Therefore, the lowest common multiple of 471,715,988,490,921 is 385012648020.
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.
471 x 715 x 988 x 490 x 921 = 150154932727800
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.
471 : 1, 3, 157, 471
715 : 1, 5, 11, 13, 55, 65, 143, 715
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,715,988,490,921, is 1.
Now, the common factors can be found like this.
471:3x 157
715:5x 11x 13
988:2x 2x 13x 19
490:2x 5x 7x 7
921:3x 307
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 13 = 390
Therefore, the value for common factors is 390.
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 = 150154932727800/(1x390)
LCM = 150154932727800/390
LCM = 385012648020
Thus, we can understand that the LCM of 471,715,988,490,921 is 385012648020.
