Given numbers are 721,533,492,999,997
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,533,492,999,997 is 1531027923516.
Find LCM of 721,533,492,999,997 with Prime Factorization
| 3 | 721, 533, 492, 999, 997 |
| 41 | 721, 533, 164, 333, 997 |
| 721, 13, 4, 333, 997 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 721 x 13 x 4 x 333 x 997 = 1531027923516
Therefore, the lowest common multiple of 721,533,492,999,997 is 1531027923516.
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.
721 x 533 x 492 x 999 x 997 = 188316434592468
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.
721 : 1, 7, 103, 721
533 : 1, 13, 41, 533
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
999 : 1, 3, 9, 27, 37, 111, 333, 999
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,533,492,999,997, is 1.
Now, the common factors can be found like this.
721:7x 103
533:13x 41
492:2x 2x 3x 41
999:3x 3x 3x 37
997:997
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 188316434592468/(1x123)
LCM = 188316434592468/123
LCM = 1531027923516
Thus, we can understand that the LCM of 721,533,492,999,997 is 1531027923516.
