The LCM of 448,891,187,770 is 33929280.
Find LCM of 448,891,187,770 with Prime Factorization
| 2 | 448, 891, 187, 770 |
| 7 | 224, 891, 187, 385 |
| 11 | 32, 891, 187, 55 |
| 32, 81, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 32 x 81 x 17 x 5 = 33929280
Therefore, the lowest common multiple of 448,891,187,770 is 33929280.
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.
448 x 891 x 187 x 770 = 57476200320
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.
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
187 : 1, 11, 17, 187
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,891,187,770, is 1.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
891:3x 3x 3x 3x 11
187:11x 17
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 11 = 1694
Therefore, the value for common factors is 1694.
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 = 57476200320/(1x1694)
LCM = 57476200320/1694
LCM = 33929280
Thus, we can understand that the LCM of 448,891,187,770 is 33929280.
