Given numbers are 990,185,550,758,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,185,550,758,974 is 33804544950.
Find LCM of 990,185,550,758,974 with Prime Factorization
| 2 | 990, 185, 550, 758, 974 |
| 5 | 495, 185, 275, 379, 487 |
| 11 | 99, 37, 55, 379, 487 |
| 9, 37, 5, 379, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 9 x 37 x 5 x 379 x 487 = 33804544950
Therefore, the lowest common multiple of 990,185,550,758,974 is 33804544950.
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 185 x 550 x 758 x 974 = 74369998890000
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
185 : 1, 5, 37, 185
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
758 : 1, 2, 379, 758
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,185,550,758,974, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
185:5x 37
550:2x 5x 5x 11
758:2x 379
974:2x 487
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 2x 5x 5x 11 = 2200
Therefore, the value for common factors is 2200.
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 = 74369998890000/(1x2200)
LCM = 74369998890000/2200
LCM = 33804544950
Thus, we can understand that the LCM of 990,185,550,758,974 is 33804544950.
