Given numbers are 791,221,478,932
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,221,478,932 is 38938800628.
Find LCM of 791,221,478,932 with Prime Factorization
| 2 | 791, 221, 478, 932 |
| 791, 221, 239, 466 |
Multiply the prime numbers at the bottom and the left side.
2 x 791 x 221 x 239 x 466 = 38938800628
Therefore, the lowest common multiple of 791,221,478,932 is 38938800628.
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.
791 x 221 x 478 x 932 = 77877601256
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.
791 : 1, 7, 113, 791
221 : 1, 13, 17, 221
478 : 1, 2, 239, 478
932 : 1, 2, 4, 233, 466, 932
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,221,478,932, is 1.
Now, the common factors can be found like this.
791:7x 113
221:13x 17
478:2x 239
932:2x 2x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 77877601256/(1x2)
LCM = 77877601256/2
LCM = 38938800628
Thus, we can understand that the LCM of 791,221,478,932 is 38938800628.
