Given numbers are 846,923,710,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 846,923,710,978 is 636399270.
Find LCM of 846,923,710,978 with Prime Factorization
| 2 | 846, 923, 710, 978 |
| 3 | 423, 923, 355, 489 |
| 71 | 141, 923, 355, 163 |
| 141, 13, 5, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 141 x 13 x 5 x 163 = 636399270
Therefore, the lowest common multiple of 846,923,710,978 is 636399270.
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 923 x 710 x 978 = 542212178040
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
923 : 1, 13, 71, 923
710 : 1, 2, 5, 10, 71, 142, 355, 710
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,923,710,978, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
923:13x 71
710:2x 5x 71
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 71 = 852
Therefore, the value for common factors is 852.
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 = 542212178040/(1x852)
LCM = 542212178040/852
LCM = 636399270
Thus, we can understand that the LCM of 846,923,710,978 is 636399270.
