Find LCM of 840,799,924,120,471 with Prime Factorization
| 2 | 840, 799, 924, 120, 471 |
| 2 | 420, 799, 462, 60, 471 |
| 2 | 210, 799, 231, 30, 471 |
| 3 | 105, 799, 231, 15, 471 |
| 5 | 35, 799, 77, 5, 157 |
| 7 | 7, 799, 77, 1, 157 |
| 1, 799, 11, 1, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 1 x 799 x 11 x 1 x 157 = 1159093320
Therefore, the lowest common multiple of 840,799,924,120,471 is 1159093320.
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.
840 x 799 x 924 x 120 x 471 = 35050981996800
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
799 : 1, 17, 47, 799
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,799,924,120,471, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
799:17x 47
924:2x 2x 3x 7x 11
120:2x 2x 2x 3x 5
471:3x 157
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 2x 2x 3x 3x 3x 5x 7 = 30240
Therefore, the value for common factors is 30240.
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 = 35050981996800/(1x30240)
LCM = 35050981996800/30240
LCM = 1159093320
Thus, we can understand that the LCM of 840,799,924,120,471 is 1159093320.
