Given numbers are 721,721,294,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,721,294,452 is 6843732.
Find LCM of 721,721,294,452 with Prime Factorization
| 2 | 721, 721, 294, 452 |
| 7 | 721, 721, 147, 226 |
| 103 | 103, 103, 21, 226 |
| 1, 1, 21, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 103 x 1 x 1 x 21 x 226 = 6843732
Therefore, the lowest common multiple of 721,721,294,452 is 6843732.
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 721 x 294 x 452 = 69080630808
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
721 : 1, 7, 103, 721
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,721,294,452, is 1.
Now, the common factors can be found like this.
721:7x 103
721:7x 103
294:2x 3x 7x 7
452:2x 2x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 103 = 10094
Therefore, the value for common factors is 10094.
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 = 69080630808/(1x10094)
LCM = 69080630808/10094
LCM = 6843732
Thus, we can understand that the LCM of 721,721,294,452 is 6843732.
