Given numbers are 846,321,978,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 846,321,978,387 is 634468698.
Find LCM of 846,321,978,387 with Prime Factorization
| 2 | 846, 321, 978, 387 |
| 3 | 423, 321, 489, 387 |
| 3 | 141, 107, 163, 129 |
| 47, 107, 163, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 107 x 163 x 43 = 634468698
Therefore, the lowest common multiple of 846,321,978,387 is 634468698.
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.
846 x 321 x 978 x 387 = 102783929076
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
321 : 1, 3, 107, 321
978 : 1, 2, 3, 6, 163, 326, 489, 978
387 : 1, 3, 9, 43, 129, 387
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,321,978,387, is 3.
Now, the common factors can be found like this.
846:2x 3x 3x 47
321:3x 107
978:2x 3x 163
387:3x 3x 43
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 3 = 54
Therefore, the value for common factors is 54.
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 = 102783929076/(3x54)
LCM = 102783929076/162
LCM = 634468698
Thus, we can understand that the LCM of 846,321,978,387 is 634468698.
