Given numbers are 658,321,851,713,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,321,851,713,784 is 312039955248.
Find LCM of 658,321,851,713,784 with Prime Factorization
| 2 | 658, 321, 851, 713, 784 |
| 7 | 329, 321, 851, 713, 392 |
| 23 | 47, 321, 851, 713, 56 |
| 47, 321, 37, 31, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 47 x 321 x 37 x 31 x 56 = 312039955248
Therefore, the lowest common multiple of 658,321,851,713,784 is 312039955248.
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.
658 x 321 x 851 x 713 x 784 = 100476865589856
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
321 : 1, 3, 107, 321
851 : 1, 23, 37, 851
713 : 1, 23, 31, 713
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 658,321,851,713,784, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
321:3x 107
851:23x 37
713:23x 31
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.
2x 7x 23 = 322
Therefore, the value for common factors is 322.
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 = 100476865589856/(1x322)
LCM = 100476865589856/322
LCM = 312039955248
Thus, we can understand that the LCM of 658,321,851,713,784 is 312039955248.
