The LCM of 281,456,779,608 is 21014304.
Find LCM of 281,456,779,608 with Prime Factorization
| 2 | 281, 456, 779, 608 |
| 2 | 281, 228, 779, 304 |
| 2 | 281, 114, 779, 152 |
| 19 | 281, 57, 779, 76 |
| 281, 3, 41, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 281 x 3 x 41 x 4 = 21014304
Therefore, the lowest common multiple of 281,456,779,608 is 21014304.
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.
281 x 456 x 779 x 608 = 60689309952
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.
281 : 1, 281
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
779 : 1, 19, 41, 779
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,456,779,608, is 1.
Now, the common factors can be found like this.
281:281
456:2x 2x 2x 3x 19
779:19x 41
608:2x 2x 2x 2x 2x 19
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 19x 19 = 2888
Therefore, the value for common factors is 2888.
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 = 60689309952/(1x2888)
LCM = 60689309952/2888
LCM = 21014304
Thus, we can understand that the LCM of 281,456,779,608 is 21014304.
