Given numbers are 721,534,618,451,879
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,534,618,451,879 is 50876905002.
Find LCM of 721,534,618,451,879 with Prime Factorization
| 2 | 721, 534, 618, 451, 879 |
| 3 | 721, 267, 309, 451, 879 |
| 103 | 721, 89, 103, 451, 293 |
| 7, 89, 1, 451, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 7 x 89 x 1 x 451 x 293 = 50876905002
Therefore, the lowest common multiple of 721,534,618,451,879 is 50876905002.
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 534 x 618 x 451 x 879 = 94325781873708
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
534 : 1, 2, 3, 6, 89, 178, 267, 534
618 : 1, 2, 3, 6, 103, 206, 309, 618
451 : 1, 11, 41, 451
879 : 1, 3, 293, 879
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,534,618,451,879, is 1.
Now, the common factors can be found like this.
721:7x 103
534:2x 3x 89
618:2x 3x 103
451:11x 41
879:3x 293
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 103 = 1854
Therefore, the value for common factors is 1854.
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 = 94325781873708/(1x1854)
LCM = 94325781873708/1854
LCM = 50876905002
Thus, we can understand that the LCM of 721,534,618,451,879 is 50876905002.
