Given numbers are 861,756,894,952
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,756,894,952 is 157025736.
Find LCM of 861,756,894,952 with Prime Factorization
| 2 | 861, 756, 894, 952 |
| 2 | 861, 378, 447, 476 |
| 3 | 861, 189, 447, 238 |
| 7 | 287, 63, 149, 238 |
| 41, 9, 149, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 41 x 9 x 149 x 34 = 157025736
Therefore, the lowest common multiple of 861,756,894,952 is 157025736.
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.
861 x 756 x 894 x 952 = 553986796608
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
894 : 1, 2, 3, 6, 149, 298, 447, 894
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,756,894,952, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
756:2x 2x 3x 3x 3x 7
894:2x 3x 149
952:2x 2x 2x 7x 17
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 3x 7x 7 = 3528
Therefore, the value for common factors is 3528.
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 = 553986796608/(1x3528)
LCM = 553986796608/3528
LCM = 157025736
Thus, we can understand that the LCM of 861,756,894,952 is 157025736.
