Given numbers are 990,455,962,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,455,962,354 is 196666470.
Find LCM of 990,455,962,354 with Prime Factorization
| 2 | 990, 455, 962, 354 |
| 3 | 495, 455, 481, 177 |
| 5 | 165, 455, 481, 59 |
| 13 | 33, 91, 481, 59 |
| 33, 7, 37, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 33 x 7 x 37 x 59 = 196666470
Therefore, the lowest common multiple of 990,455,962,354 is 196666470.
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.
990 x 455 x 962 x 354 = 153399846600
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
455 : 1, 5, 7, 13, 35, 65, 91, 455
962 : 1, 2, 13, 26, 37, 74, 481, 962
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,455,962,354, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
455:5x 7x 13
962:2x 13x 37
354:2x 3x 59
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 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 153399846600/(1x780)
LCM = 153399846600/780
LCM = 196666470
Thus, we can understand that the LCM of 990,455,962,354 is 196666470.
