Given numbers are 985,730,781,160,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,730,781,160,217 is 389959797920.
Find LCM of 985,730,781,160,217 with Prime Factorization
| 2 | 985, 730, 781, 160, 217 |
| 5 | 985, 365, 781, 80, 217 |
| 197, 73, 781, 16, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 197 x 73 x 781 x 16 x 217 = 389959797920
Therefore, the lowest common multiple of 985,730,781,160,217 is 389959797920.
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.
985 x 730 x 781 x 160 x 217 = 19497989896000
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.
985 : 1, 5, 197, 985
730 : 1, 2, 5, 10, 73, 146, 365, 730
781 : 1, 11, 71, 781
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,730,781,160,217, is 1.
Now, the common factors can be found like this.
985:5x 197
730:2x 5x 73
781:11x 71
160:2x 2x 2x 2x 2x 5
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 19497989896000/(1x50)
LCM = 19497989896000/50
LCM = 389959797920
Thus, we can understand that the LCM of 985,730,781,160,217 is 389959797920.
