Given numbers are 838,659,956,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,659,956,816 is 53850221904.
Find LCM of 838,659,956,816 with Prime Factorization
| 2 | 838, 659, 956, 816 |
| 2 | 419, 659, 478, 408 |
| 419, 659, 239, 204 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 419 x 659 x 239 x 204 = 53850221904
Therefore, the lowest common multiple of 838,659,956,816 is 53850221904.
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.
838 x 659 x 956 x 816 = 430801775232
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.
838 : 1, 2, 419, 838
659 : 1, 659
956 : 1, 2, 4, 239, 478, 956
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 838,659,956,816, is 1.
Now, the common factors can be found like this.
838:2x 419
659:659
956:2x 2x 239
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 2 = 8
Therefore, the value for common factors is 8.
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 = 430801775232/(1x8)
LCM = 430801775232/8
LCM = 53850221904
Thus, we can understand that the LCM of 838,659,956,816 is 53850221904.
