The LCM of 357,918,381,784 is 45701712.
Find LCM of 357,918,381,784 with Prime Factorization
| 2 | 357, 918, 381, 784 |
| 3 | 357, 459, 381, 392 |
| 7 | 119, 153, 127, 392 |
| 17 | 17, 153, 127, 56 |
| 1, 9, 127, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 1 x 9 x 127 x 56 = 45701712
Therefore, the lowest common multiple of 357,918,381,784 is 45701712.
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.
357 x 918 x 381 x 784 = 97893067104
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
381 : 1, 3, 127, 381
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,918,381,784, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
918:2x 3x 3x 3x 17
381:3x 127
784:2x 2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 17 = 2142
Therefore, the value for common factors is 2142.
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 = 97893067104/(1x2142)
LCM = 97893067104/2142
LCM = 45701712
Thus, we can understand that the LCM of 357,918,381,784 is 45701712.
