Given numbers are 978,730,684,877
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,730,684,877 is 35689146660.
Find LCM of 978,730,684,877 with Prime Factorization
| 2 | 978, 730, 684, 877 |
| 3 | 489, 365, 342, 877 |
| 163, 365, 114, 877 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 365 x 114 x 877 = 35689146660
Therefore, the lowest common multiple of 978,730,684,877 is 35689146660.
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.
978 x 730 x 684 x 877 = 428269759920
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
730 : 1, 2, 5, 10, 73, 146, 365, 730
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
877 : 1, 877
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,730,684,877, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
730:2x 5x 73
684:2x 2x 3x 3x 19
877:877
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 3 = 12
Therefore, the value for common factors is 12.
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 = 428269759920/(1x12)
LCM = 428269759920/12
LCM = 35689146660
Thus, we can understand that the LCM of 978,730,684,877 is 35689146660.
