Given numbers are 862,322,641,280,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,322,641,280,816 is 181476894480.
Find LCM of 862,322,641,280,816 with Prime Factorization
| 2 | 862, 322, 641, 280, 816 |
| 2 | 431, 161, 641, 140, 408 |
| 2 | 431, 161, 641, 70, 204 |
| 7 | 431, 161, 641, 35, 102 |
| 431, 23, 641, 5, 102 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 431 x 23 x 641 x 5 x 102 = 181476894480
Therefore, the lowest common multiple of 862,322,641,280,816 is 181476894480.
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.
862 x 322 x 641 x 280 x 816 = 40650824363520
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.
862 : 1, 2, 431, 862
322 : 1, 2, 7, 14, 23, 46, 161, 322
641 : 1, 641
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
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 862,322,641,280,816, is 1.
Now, the common factors can be found like this.
862:2x 431
322:2x 7x 23
641:641
280:2x 2x 2x 5x 7
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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 40650824363520/(1x224)
LCM = 40650824363520/224
LCM = 181476894480
Thus, we can understand that the LCM of 862,322,641,280,816 is 181476894480.
