Find LCM of 208,678,821,480,936 with Prime Factorization
| 2 | 208, 678, 821, 480, 936 |
| 2 | 104, 339, 821, 240, 468 |
| 2 | 52, 339, 821, 120, 234 |
| 2 | 26, 339, 821, 60, 117 |
| 3 | 13, 339, 821, 30, 117 |
| 13 | 13, 113, 821, 10, 39 |
| 1, 113, 821, 10, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 1 x 113 x 821 x 10 x 3 = 1736710560
Therefore, the lowest common multiple of 208,678,821,480,936 is 1736710560.
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 678 x 821 x 480 x 936 = 52017954693120
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
678 : 1, 2, 3, 6, 113, 226, 339, 678
821 : 1, 821
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,678,821,480,936, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
678:2x 3x 113
821:821
480:2x 2x 2x 2x 2x 3x 5
936:2x 2x 2x 3x 3x 13
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 2x 2x 2x 3x 3x 13 = 29952
Therefore, the value for common factors is 29952.
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 = 52017954693120/(1x29952)
LCM = 52017954693120/29952
LCM = 1736710560
Thus, we can understand that the LCM of 208,678,821,480,936 is 1736710560.
