Given numbers are 458,451,529,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 458,451,529,784 is 42833519344.
Find LCM of 458,451,529,784 with Prime Factorization
| 2 | 458, 451, 529, 784 |
| 229, 451, 529, 392 |
Multiply the prime numbers at the bottom and the left side.
2 x 229 x 451 x 529 x 392 = 42833519344
Therefore, the lowest common multiple of 458,451,529,784 is 42833519344.
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.
458 x 451 x 529 x 784 = 85667038688
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.
458 : 1, 2, 229, 458
451 : 1, 11, 41, 451
529 : 1, 23, 529
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 458,451,529,784, is 1.
Now, the common factors can be found like this.
458:2x 229
451:11x 41
529:23x 23
784:2x 2x 2x 2x 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.
2 = 2
Therefore, the value for common factors is 2.
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 = 85667038688/(1x2)
LCM = 85667038688/2
LCM = 42833519344
Thus, we can understand that the LCM of 458,451,529,784 is 42833519344.
