Given numbers are 802,868,722,798,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,868,722,798,856 is 80668935816.
Find LCM of 802,868,722,798,856 with Prime Factorization
| 2 | 802, 868, 722, 798, 856 |
| 2 | 401, 434, 361, 399, 428 |
| 7 | 401, 217, 361, 399, 214 |
| 19 | 401, 31, 361, 57, 214 |
| 401, 31, 19, 3, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 401 x 31 x 19 x 3 x 214 = 80668935816
Therefore, the lowest common multiple of 802,868,722,798,856 is 80668935816.
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.
802 x 868 x 722 x 798 x 856 = 343326990832896
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.
802 : 1, 2, 401, 802
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
722 : 1, 2, 19, 38, 361, 722
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
856 : 1, 2, 4, 8, 107, 214, 428, 856
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,868,722,798,856, is 2.
Now, the common factors can be found like this.
802:2x 401
868:2x 2x 7x 31
722:2x 19x 19
798:2x 3x 7x 19
856:2x 2x 2x 107
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 7x 19 = 2128
Therefore, the value for common factors is 2128.
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 = 343326990832896/(2x2128)
LCM = 343326990832896/4256
LCM = 80668935816
Thus, we can understand that the LCM of 802,868,722,798,856 is 80668935816.
