Given numbers are 7,963,428,348
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,963,428,348 is 781956.
Find LCM of 7,963,428,348 with Prime Factorization
| 2 | 7, 963, 428, 348 |
| 2 | 7, 963, 214, 174 |
| 3 | 7, 963, 107, 87 |
| 107 | 7, 321, 107, 29 |
| 7, 3, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 7 x 3 x 1 x 29 = 781956
Therefore, the lowest common multiple of 7,963,428,348 is 781956.
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.
7 x 963 x 428 x 348 = 1004031504
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.
7 : 1, 7
963 : 1, 3, 9, 107, 321, 963
428 : 1, 2, 4, 107, 214, 428
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,963,428,348, is 1.
Now, the common factors can be found like this.
7:7
963:3x 3x 107
428:2x 2x 107
348:2x 2x 3x 29
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 3x 107 = 1284
Therefore, the value for common factors is 1284.
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 = 1004031504/(1x1284)
LCM = 1004031504/1284
LCM = 781956
Thus, we can understand that the LCM of 7,963,428,348 is 781956.
