Find LCM of 784,147,927,748,344 with Prime Factorization
| 2 | 784, 147, 927, 748, 344 |
| 2 | 392, 147, 927, 374, 172 |
| 2 | 196, 147, 927, 187, 86 |
| 3 | 98, 147, 927, 187, 43 |
| 7 | 98, 49, 309, 187, 43 |
| 7 | 14, 7, 309, 187, 43 |
| 2, 1, 309, 187, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 2 x 1 x 309 x 187 x 43 = 5843941488
Therefore, the lowest common multiple of 784,147,927,748,344 is 5843941488.
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.
784 x 147 x 927 x 748 x 344 = 27489900759552
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
147 : 1, 3, 7, 21, 49, 147
927 : 1, 3, 9, 103, 309, 927
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,147,927,748,344, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
147:3x 7x 7
927:3x 3x 103
748:2x 2x 11x 17
344:2x 2x 2x 43
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 2x 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 27489900759552/(1x4704)
LCM = 27489900759552/4704
LCM = 5843941488
Thus, we can understand that the LCM of 784,147,927,748,344 is 5843941488.
