Given numbers are 781,352,243,570,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,352,243,570,964 is 139042617120.
Find LCM of 781,352,243,570,964 with Prime Factorization
| 2 | 781, 352, 243, 570, 964 |
| 2 | 781, 176, 243, 285, 482 |
| 3 | 781, 88, 243, 285, 241 |
| 11 | 781, 88, 81, 95, 241 |
| 71, 8, 81, 95, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 71 x 8 x 81 x 95 x 241 = 139042617120
Therefore, the lowest common multiple of 781,352,243,570,964 is 139042617120.
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.
781 x 352 x 243 x 570 x 964 = 36707250919680
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.
781 : 1, 11, 71, 781
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
243 : 1, 3, 9, 27, 81, 243
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
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 781,352,243,570,964, is 1.
Now, the common factors can be found like this.
781:11x 71
352:2x 2x 2x 2x 2x 11
243:3x 3x 3x 3x 3
570:2x 3x 5x 19
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 36707250919680/(1x264)
LCM = 36707250919680/264
LCM = 139042617120
Thus, we can understand that the LCM of 781,352,243,570,964 is 139042617120.
