Given numbers are 440,155,806,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,155,806,746 is 66140360.
Find LCM of 440,155,806,746 with Prime Factorization
| 2 | 440, 155, 806, 746 |
| 5 | 220, 155, 403, 373 |
| 31 | 44, 31, 403, 373 |
| 44, 1, 13, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 44 x 1 x 13 x 373 = 66140360
Therefore, the lowest common multiple of 440,155,806,746 is 66140360.
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.
440 x 155 x 806 x 746 = 41007023200
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
155 : 1, 5, 31, 155
806 : 1, 2, 13, 26, 31, 62, 403, 806
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,155,806,746, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
155:5x 31
806:2x 13x 31
746:2x 373
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 5x 31 = 620
Therefore, the value for common factors is 620.
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 = 41007023200/(1x620)
LCM = 41007023200/620
LCM = 66140360
Thus, we can understand that the LCM of 440,155,806,746 is 66140360.
