Given numbers are 613,306,948,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,306,948,428 is 3171193668.
Find LCM of 613,306,948,428 with Prime Factorization
| 2 | 613, 306, 948, 428 |
| 2 | 613, 153, 474, 214 |
| 3 | 613, 153, 237, 107 |
| 613, 51, 79, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 613 x 51 x 79 x 107 = 3171193668
Therefore, the lowest common multiple of 613,306,948,428 is 3171193668.
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.
613 x 306 x 948 x 428 = 76108648032
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.
613 : 1, 613
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,306,948,428, is 1.
Now, the common factors can be found like this.
613:613
306:2x 3x 3x 17
948:2x 2x 3x 79
428:2x 2x 107
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 3 = 24
Therefore, the value for common factors is 24.
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 = 76108648032/(1x24)
LCM = 76108648032/24
LCM = 3171193668
Thus, we can understand that the LCM of 613,306,948,428 is 3171193668.
