The LCM of 748,240,561,609,747 is 2268549360.
Find LCM of 748,240,561,609,747 with Prime Factorization
| 2 | 748, 240, 561, 609, 747 |
| 2 | 374, 120, 561, 609, 747 |
| 3 | 187, 60, 561, 609, 747 |
| 11 | 187, 20, 187, 203, 249 |
| 17 | 17, 20, 17, 203, 249 |
| 1, 20, 1, 203, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 1 x 20 x 1 x 203 x 249 = 2268549360
Therefore, the lowest common multiple of 748,240,561,609,747 is 2268549360.
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.
748 x 240 x 561 x 609 x 747 = 45815622874560
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
561 : 1, 3, 11, 17, 33, 51, 187, 561
609 : 1, 3, 7, 21, 29, 87, 203, 609
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,240,561,609,747, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
240:2x 2x 2x 2x 3x 5
561:3x 11x 17
609:3x 7x 29
747:3x 3x 83
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 3x 3x 3x 11x 17 = 20196
Therefore, the value for common factors is 20196.
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 = 45815622874560/(1x20196)
LCM = 45815622874560/20196
LCM = 2268549360
Thus, we can understand that the LCM of 748,240,561,609,747 is 2268549360.
