Given numbers are 803,981,874,506,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,981,874,506,490 is 168679408590.
Find LCM of 803,981,874,506,490 with Prime Factorization
| 2 | 803, 981, 874, 506, 490 |
| 11 | 803, 981, 437, 253, 245 |
| 23 | 73, 981, 437, 23, 245 |
| 73, 981, 19, 1, 245 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 73 x 981 x 19 x 1 x 245 = 168679408590
Therefore, the lowest common multiple of 803,981,874,506,490 is 168679408590.
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.
803 x 981 x 874 x 506 x 490 = 170703561493080
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.
803 : 1, 11, 73, 803
981 : 1, 3, 9, 109, 327, 981
874 : 1, 2, 19, 23, 38, 46, 437, 874
506 : 1, 2, 11, 22, 23, 46, 253, 506
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,981,874,506,490, is 1.
Now, the common factors can be found like this.
803:11x 73
981:3x 3x 109
874:2x 19x 23
506:2x 11x 23
490:2x 5x 7x 7
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 11x 23 = 1012
Therefore, the value for common factors is 1012.
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 = 170703561493080/(1x1012)
LCM = 170703561493080/1012
LCM = 168679408590
Thus, we can understand that the LCM of 803,981,874,506,490 is 168679408590.
