Given numbers are 782,984,921,307
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,984,921,307 is 118116408.
Find LCM of 782,984,921,307 with Prime Factorization
| 2 | 782, 984, 921, 307 |
| 3 | 391, 492, 921, 307 |
| 307 | 391, 164, 307, 307 |
| 391, 164, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 391 x 164 x 1 x 1 = 118116408
Therefore, the lowest common multiple of 782,984,921,307 is 118116408.
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.
782 x 984 x 921 x 307 = 217570423536
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
921 : 1, 3, 307, 921
307 : 1, 307
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,984,921,307, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
984:2x 2x 2x 3x 41
921:3x 307
307:307
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 307 = 1842
Therefore, the value for common factors is 1842.
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 = 217570423536/(1x1842)
LCM = 217570423536/1842
LCM = 118116408
Thus, we can understand that the LCM of 782,984,921,307 is 118116408.
