Given numbers are 321,531,663,826
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,531,663,826 is 175791798.
Find LCM of 321,531,663,826 with Prime Factorization
| 3 | 321, 531, 663, 826 |
| 59 | 107, 177, 221, 826 |
| 107, 3, 221, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 107 x 3 x 221 x 14 = 175791798
Therefore, the lowest common multiple of 321,531,663,826 is 175791798.
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.
321 x 531 x 663 x 826 = 93345444738
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.
321 : 1, 3, 107, 321
531 : 1, 3, 9, 59, 177, 531
663 : 1, 3, 13, 17, 39, 51, 221, 663
826 : 1, 2, 7, 14, 59, 118, 413, 826
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,531,663,826, is 1.
Now, the common factors can be found like this.
321:3x 107
531:3x 3x 59
663:3x 13x 17
826:2x 7x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 59 = 531
Therefore, the value for common factors is 531.
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 = 93345444738/(1x531)
LCM = 93345444738/531
LCM = 175791798
Thus, we can understand that the LCM of 321,531,663,826 is 175791798.
