Given numbers are 473,814,969,721,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,814,969,721,665 is 122270561490.
Find LCM of 473,814,969,721,665 with Prime Factorization
| 7 | 473, 814, 969, 721, 665 |
| 11 | 473, 814, 969, 103, 95 |
| 19 | 43, 74, 969, 103, 95 |
| 43, 74, 51, 103, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 19 x 43 x 74 x 51 x 103 x 5 = 122270561490
Therefore, the lowest common multiple of 473,814,969,721,665 is 122270561490.
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.
473 x 814 x 969 x 721 x 665 = 178881831459870
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.
473 : 1, 11, 43, 473
814 : 1, 2, 11, 22, 37, 74, 407, 814
969 : 1, 3, 17, 19, 51, 57, 323, 969
721 : 1, 7, 103, 721
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,814,969,721,665, is 1.
Now, the common factors can be found like this.
473:11x 43
814:2x 11x 37
969:3x 17x 19
721:7x 103
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 19 = 1463
Therefore, the value for common factors is 1463.
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 = 178881831459870/(1x1463)
LCM = 178881831459870/1463
LCM = 122270561490
Thus, we can understand that the LCM of 473,814,969,721,665 is 122270561490.
