Given numbers are 811,140,783,411,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,140,783,411,964 is 2935271390940.
Find LCM of 811,140,783,411,964 with Prime Factorization
| 2 | 811, 140, 783, 411, 964 |
| 2 | 811, 70, 783, 411, 482 |
| 3 | 811, 35, 783, 411, 241 |
| 811, 35, 261, 137, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 811 x 35 x 261 x 137 x 241 = 2935271390940
Therefore, the lowest common multiple of 811,140,783,411,964 is 2935271390940.
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.
811 x 140 x 783 x 411 x 964 = 35223256691280
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.
811 : 1, 811
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
783 : 1, 3, 9, 27, 29, 87, 261, 783
411 : 1, 3, 137, 411
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,140,783,411,964, is 1.
Now, the common factors can be found like this.
811:811
140:2x 2x 5x 7
783:3x 3x 3x 29
411:3x 137
964:2x 2x 241
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 = 35223256691280/(1x12)
LCM = 35223256691280/12
LCM = 2935271390940
Thus, we can understand that the LCM of 811,140,783,411,964 is 2935271390940.
