The LCM of 798,719,832,392 is 1670794944.
Find LCM of 798,719,832,392 with Prime Factorization
| 2 | 798, 719, 832, 392 |
| 2 | 399, 719, 416, 196 |
| 2 | 399, 719, 208, 98 |
| 7 | 399, 719, 104, 49 |
| 57, 719, 104, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 57 x 719 x 104 x 7 = 1670794944
Therefore, the lowest common multiple of 798,719,832,392 is 1670794944.
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.
798 x 719 x 832 x 392 = 187129033728
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
719 : 1, 719
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
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 798,719,832,392, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
719:719
832:2x 2x 2x 2x 2x 2x 13
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 7 = 112
Therefore, the value for common factors is 112.
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 = 187129033728/(1x112)
LCM = 187129033728/112
LCM = 1670794944
Thus, we can understand that the LCM of 798,719,832,392 is 1670794944.
