Given numbers are 940,810,561,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 940,810,561,312 is 370192680.
Find LCM of 940,810,561,312 with Prime Factorization
| 2 | 940, 810, 561, 312 |
| 2 | 470, 405, 561, 156 |
| 3 | 235, 405, 561, 78 |
| 5 | 235, 135, 187, 26 |
| 47, 27, 187, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 27 x 187 x 26 = 370192680
Therefore, the lowest common multiple of 940,810,561,312 is 370192680.
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.
940 x 810 x 561 x 312 = 133269364800
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
561 : 1, 3, 11, 17, 33, 51, 187, 561
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,810,561,312, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
810:2x 3x 3x 3x 3x 5
561:3x 11x 17
312:2x 2x 2x 3x 13
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 5 = 360
Therefore, the value for common factors is 360.
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 = 133269364800/(1x360)
LCM = 133269364800/360
LCM = 370192680
Thus, we can understand that the LCM of 940,810,561,312 is 370192680.
