Given numbers are 399,354,740,378,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,354,740,378,165 is 1724613660.
Find LCM of 399,354,740,378,165 with Prime Factorization
| 2 | 399, 354, 740, 378, 165 |
| 3 | 399, 177, 370, 189, 165 |
| 5 | 133, 59, 370, 63, 55 |
| 7 | 133, 59, 74, 63, 11 |
| 19, 59, 74, 9, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 19 x 59 x 74 x 9 x 11 = 1724613660
Therefore, the lowest common multiple of 399,354,740,378,165 is 1724613660.
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.
399 x 354 x 740 x 378 x 165 = 6519039634800
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
354 : 1, 2, 3, 6, 59, 118, 177, 354
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,354,740,378,165, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
354:2x 3x 59
740:2x 2x 5x 37
378:2x 3x 3x 3x 7
165:3x 5x 11
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 3x 3x 3x 5x 7 = 3780
Therefore, the value for common factors is 3780.
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 = 6519039634800/(1x3780)
LCM = 6519039634800/3780
LCM = 1724613660
Thus, we can understand that the LCM of 399,354,740,378,165 is 1724613660.
