Given numbers are 721,381,508,332
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,381,508,332 is 91200732.
Find LCM of 721,381,508,332 with Prime Factorization
| 2 | 721, 381, 508, 332 |
| 2 | 721, 381, 254, 166 |
| 127 | 721, 381, 127, 83 |
| 721, 3, 1, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 127 x 721 x 3 x 1 x 83 = 91200732
Therefore, the lowest common multiple of 721,381,508,332 is 91200732.
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.
721 x 381 x 508 x 332 = 46329971856
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.
721 : 1, 7, 103, 721
381 : 1, 3, 127, 381
508 : 1, 2, 4, 127, 254, 508
332 : 1, 2, 4, 83, 166, 332
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,381,508,332, is 1.
Now, the common factors can be found like this.
721:7x 103
381:3x 127
508:2x 2x 127
332:2x 2x 83
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 127 = 508
Therefore, the value for common factors is 508.
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 = 46329971856/(1x508)
LCM = 46329971856/508
LCM = 91200732
Thus, we can understand that the LCM of 721,381,508,332 is 91200732.
