Given numbers are 956,156,239,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 956,156,239,428 is 3989388.
Find LCM of 956,156,239,428 with Prime Factorization
| 2 | 956, 156, 239, 428 |
| 2 | 478, 78, 239, 214 |
| 239 | 239, 39, 239, 107 |
| 1, 39, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 239 x 1 x 39 x 1 x 107 = 3989388
Therefore, the lowest common multiple of 956,156,239,428 is 3989388.
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.
956 x 156 x 239 x 428 = 15255419712
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.
956 : 1, 2, 4, 239, 478, 956
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
239 : 1, 239
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 956,156,239,428, is 1.
Now, the common factors can be found like this.
956:2x 2x 239
156:2x 2x 3x 13
239:239
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 2x 239 = 3824
Therefore, the value for common factors is 3824.
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 = 15255419712/(1x3824)
LCM = 15255419712/3824
LCM = 3989388
Thus, we can understand that the LCM of 956,156,239,428 is 3989388.
