Given numbers are 756,166,412,779,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,166,412,779,656 is 20138845104.
Find LCM of 756,166,412,779,656 with Prime Factorization
| 2 | 756, 166, 412, 779, 656 |
| 2 | 378, 83, 206, 779, 328 |
| 41 | 189, 83, 103, 779, 164 |
| 189, 83, 103, 19, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 189 x 83 x 103 x 19 x 4 = 20138845104
Therefore, the lowest common multiple of 756,166,412,779,656 is 20138845104.
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.
756 x 166 x 412 x 779 x 656 = 26422164776448
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.
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
166 : 1, 2, 83, 166
412 : 1, 2, 4, 103, 206, 412
779 : 1, 19, 41, 779
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,166,412,779,656, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
166:2x 83
412:2x 2x 103
779:19x 41
656:2x 2x 2x 2x 41
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 2x 2x 41 = 1312
Therefore, the value for common factors is 1312.
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 = 26422164776448/(1x1312)
LCM = 26422164776448/1312
LCM = 20138845104
Thus, we can understand that the LCM of 756,166,412,779,656 is 20138845104.
