Find LCM of 981,709,632,975,816 with Prime Factorization
| 2 | 981, 709, 632, 975, 816 |
| 2 | 981, 709, 316, 975, 408 |
| 2 | 981, 709, 158, 975, 204 |
| 3 | 981, 709, 79, 975, 102 |
| 327, 709, 79, 325, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 327 x 709 x 79 x 325 x 34 = 4857296324400
Therefore, the lowest common multiple of 981,709,632,975,816 is 4857296324400.
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.
981 x 709 x 632 x 975 x 816 = 349725335356800
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.
981 : 1, 3, 9, 109, 327, 981
709 : 1, 709
632 : 1, 2, 4, 8, 79, 158, 316, 632
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,709,632,975,816, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
709:709
632:2x 2x 2x 79
975:3x 5x 5x 13
816:2x 2x 2x 2x 3x 17
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 349725335356800/(1x72)
LCM = 349725335356800/72
LCM = 4857296324400
Thus, we can understand that the LCM of 981,709,632,975,816 is 4857296324400.
