Find LCM of 208,861,546,995 with Prime Factorization
| 2 | 208, 861, 546, 995 |
| 3 | 104, 861, 273, 995 |
| 7 | 104, 287, 91, 995 |
| 13 | 104, 41, 13, 995 |
| 8, 41, 1, 995 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 8 x 41 x 1 x 995 = 178192560
Therefore, the lowest common multiple of 208,861,546,995 is 178192560.
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.
208 x 861 x 546 x 995 = 97293137760
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
861 : 1, 3, 7, 21, 41, 123, 287, 861
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
995 : 1, 5, 199, 995
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,861,546,995, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
861:3x 7x 41
546:2x 3x 7x 13
995:5x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 97293137760/(1x546)
LCM = 97293137760/546
LCM = 178192560
Thus, we can understand that the LCM of 208,861,546,995 is 178192560.
