Find LCM of 981,794,518,833,782 with Prime Factorization
2 | 981, 794, 518, 833, 782 |
7 | 981, 397, 259, 833, 391 |
17 | 981, 397, 37, 119, 391 |
981, 397, 37, 7, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 981 x 397 x 37 x 7 x 23 = 552158893062
Therefore, the lowest common multiple of 981,794,518,833,782 is 552158893062.
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 794 x 518 x 833 x 782 = 262827633097512
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
794 : 1, 2, 397, 794
518 : 1, 2, 7, 14, 37, 74, 259, 518
833 : 1, 7, 17, 49, 119, 833
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,794,518,833,782, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
794:2x 397
518:2x 7x 37
833:7x 7x 17
782:2x 17x 23
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 7x 17 = 476
Therefore, the value for common factors is 476.
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 = 262827633097512/(1x476)
LCM = 262827633097512/476
LCM = 552158893062
Thus, we can understand that the LCM of 981,794,518,833,782 is 552158893062.
