Given numbers are 911,128,689,607,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 911,128,689,607,940 is 11460514682240.
Find LCM of 911,128,689,607,940 with Prime Factorization
| 2 | 911, 128, 689, 607, 940 |
| 2 | 911, 64, 689, 607, 470 |
| 911, 32, 689, 607, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 911 x 32 x 689 x 607 x 235 = 11460514682240
Therefore, the lowest common multiple of 911,128,689,607,940 is 11460514682240.
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.
911 x 128 x 689 x 607 x 940 = 45842058728960
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.
911 : 1, 911
128 : 1, 2, 4, 8, 16, 32, 64, 128
689 : 1, 13, 53, 689
607 : 1, 607
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,128,689,607,940, is 1.
Now, the common factors can be found like this.
911:911
128:2x 2x 2x 2x 2x 2x 2
689:13x 53
607:607
940:2x 2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 45842058728960/(1x4)
LCM = 45842058728960/4
LCM = 11460514682240
Thus, we can understand that the LCM of 911,128,689,607,940 is 11460514682240.
