Given numbers are 763,765,493,884,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,765,493,884,721 is 90661842180.
Find LCM of 763,765,493,884,721 with Prime Factorization
| 7 | 763, 765, 493, 884, 721 |
| 17 | 109, 765, 493, 884, 103 |
| 109, 45, 29, 52, 103 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 109 x 45 x 29 x 52 x 103 = 90661842180
Therefore, the lowest common multiple of 763,765,493,884,721 is 90661842180.
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.
763 x 765 x 493 x 884 x 721 = 183408906730140
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.
763 : 1, 7, 109, 763
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
493 : 1, 17, 29, 493
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,765,493,884,721, is 1.
Now, the common factors can be found like this.
763:7x 109
765:3x 3x 5x 17
493:17x 29
884:2x 2x 13x 17
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 17x 17 = 2023
Therefore, the value for common factors is 2023.
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 = 183408906730140/(1x2023)
LCM = 183408906730140/2023
LCM = 90661842180
Thus, we can understand that the LCM of 763,765,493,884,721 is 90661842180.
