Find LCM of 598,781,784,392 with Prime Factorization
| 2 | 598, 781, 784, 392 |
| 2 | 299, 781, 392, 196 |
| 2 | 299, 781, 98, 196 |
| 7 | 299, 781, 49, 98 |
| 7 | 299, 781, 7, 14 |
| 299, 781, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 299 x 781 x 1 x 2 = 183078896
Therefore, the lowest common multiple of 598,781,784,392 is 183078896.
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.
598 x 781 x 784 x 392 = 143533854464
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
781 : 1, 11, 71, 781
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,781,784,392, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
781:11x 71
784:2x 2x 2x 2x 7x 7
392:2x 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 2x 2x 2x 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 143533854464/(1x784)
LCM = 143533854464/784
LCM = 183078896
Thus, we can understand that the LCM of 598,781,784,392 is 183078896.
