Given numbers are 361,378,909,730
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,378,909,730 is 5030524170.
Find LCM of 361,378,909,730 with Prime Factorization
| 2 | 361, 378, 909, 730 |
| 3 | 361, 189, 909, 365 |
| 3 | 361, 63, 303, 365 |
| 361, 21, 101, 365 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 361 x 21 x 101 x 365 = 5030524170
Therefore, the lowest common multiple of 361,378,909,730 is 5030524170.
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.
361 x 378 x 909 x 730 = 90549435060
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.
361 : 1, 19, 361
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
909 : 1, 3, 9, 101, 303, 909
730 : 1, 2, 5, 10, 73, 146, 365, 730
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,378,909,730, is 1.
Now, the common factors can be found like this.
361:19x 19
378:2x 3x 3x 3x 7
909:3x 3x 101
730:2x 5x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 90549435060/(1x18)
LCM = 90549435060/18
LCM = 5030524170
Thus, we can understand that the LCM of 361,378,909,730 is 5030524170.
