Given numbers are 990,748,534,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,748,534,330 is 2995740.
Find LCM of 990,748,534,330 with Prime Factorization
| 2 | 990, 748, 534, 330 |
| 3 | 495, 374, 267, 165 |
| 5 | 55, 374, 89, 165 |
| 11 | 11, 374, 89, 33 |
| 1, 34, 89, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 1 x 34 x 89 x 3 = 2995740
Therefore, the lowest common multiple of 990,748,534,330 is 2995740.
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 748 x 534 x 330 = 130494434400
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
534 : 1, 2, 3, 6, 89, 178, 267, 534
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,748,534,330, is 2.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
748:2x 2x 11x 17
534:2x 3x 89
330:2x 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 5x 11x 11 = 21780
Therefore, the value for common factors is 21780.
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 = 130494434400/(2x21780)
LCM = 130494434400/43560
LCM = 2995740
Thus, we can understand that the LCM of 990,748,534,330 is 2995740.
