The LCM of 144,715,770,905 is 130450320.
Find LCM of 144,715,770,905 with Prime Factorization
| 2 | 144, 715, 770, 905 |
| 5 | 72, 715, 385, 905 |
| 11 | 72, 143, 77, 181 |
| 72, 13, 7, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 72 x 13 x 7 x 181 = 130450320
Therefore, the lowest common multiple of 144,715,770,905 is 130450320.
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.
144 x 715 x 770 x 905 = 71747676000
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
715 : 1, 5, 11, 13, 55, 65, 143, 715
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,715,770,905, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
715:5x 11x 13
770:2x 5x 7x 11
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11 = 550
Therefore, the value for common factors is 550.
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 = 71747676000/(1x550)
LCM = 71747676000/550
LCM = 130450320
Thus, we can understand that the LCM of 144,715,770,905 is 130450320.
