Given numbers are 921,649,956,423,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,649,956,423,298 is 12005150264316.
Find LCM of 921,649,956,423,298 with Prime Factorization
| 2 | 921, 649, 956, 423, 298 |
| 3 | 921, 649, 478, 423, 149 |
| 307, 649, 478, 141, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 649 x 478 x 141 x 149 = 12005150264316
Therefore, the lowest common multiple of 921,649,956,423,298 is 12005150264316.
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.
921 x 649 x 956 x 423 x 298 = 72030901585896
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.
921 : 1, 3, 307, 921
649 : 1, 11, 59, 649
956 : 1, 2, 4, 239, 478, 956
423 : 1, 3, 9, 47, 141, 423
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,649,956,423,298, is 1.
Now, the common factors can be found like this.
921:3x 307
649:11x 59
956:2x 2x 239
423:3x 3x 47
298:2x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 72030901585896/(1x6)
LCM = 72030901585896/6
LCM = 12005150264316
Thus, we can understand that the LCM of 921,649,956,423,298 is 12005150264316.
