Find LCM of 798,397,868,451,852 with Prime Factorization
2 | 798, 397, 868, 451, 852 |
2 | 399, 397, 434, 451, 426 |
3 | 399, 397, 217, 451, 213 |
7 | 133, 397, 217, 451, 71 |
19, 397, 31, 451, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 397 x 31 x 451 x 71 = 628955585412
Therefore, the lowest common multiple of 798,397,868,451,852 is 628955585412.
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 397 x 868 x 451 x 852 = 105664538349216
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
397 : 1, 397
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
451 : 1, 11, 41, 451
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,397,868,451,852, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
397:397
868:2x 2x 7x 31
451:11x 41
852:2x 2x 3x 71
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 7 = 168
Therefore, the value for common factors is 168.
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 = 105664538349216/(1x168)
LCM = 105664538349216/168
LCM = 628955585412
Thus, we can understand that the LCM of 798,397,868,451,852 is 628955585412.
