Given numbers are 763,442,399,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,442,399,213 is 1364834562.
Find LCM of 763,442,399,213 with Prime Factorization
| 3 | 763, 442, 399, 213 |
| 7 | 763, 442, 133, 71 |
| 109, 442, 19, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 109 x 442 x 19 x 71 = 1364834562
Therefore, the lowest common multiple of 763,442,399,213 is 1364834562.
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.
763 x 442 x 399 x 213 = 28661525802
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.
763 : 1, 7, 109, 763
442 : 1, 2, 13, 17, 26, 34, 221, 442
399 : 1, 3, 7, 19, 21, 57, 133, 399
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,442,399,213, is 1.
Now, the common factors can be found like this.
763:7x 109
442:2x 13x 17
399:3x 7x 19
213:3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 28661525802/(1x21)
LCM = 28661525802/21
LCM = 1364834562
Thus, we can understand that the LCM of 763,442,399,213 is 1364834562.
