Find LCM of 448,121,305,378,618 with Prime Factorization
| 2 | 448, 121, 305, 378, 618 |
| 3 | 224, 121, 305, 189, 309 |
| 7 | 224, 121, 305, 63, 103 |
| 32, 121, 305, 9, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 32 x 121 x 305 x 9 x 103 = 45979496640
Therefore, the lowest common multiple of 448,121,305,378,618 is 45979496640.
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 121 x 305 x 378 x 618 = 3862277717760
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
121 : 1, 11, 121
305 : 1, 5, 61, 305
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,121,305,378,618, is 1.
Now, the common factors can be found like this.
448:2x 2x 2x 2x 2x 2x 7
121:11x 11
305:5x 61
378:2x 3x 3x 3x 7
618:2x 3x 103
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 7 = 84
Therefore, the value for common factors is 84.
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 = 3862277717760/(1x84)
LCM = 3862277717760/84
LCM = 45979496640
Thus, we can understand that the LCM of 448,121,305,378,618 is 45979496640.
