Given numbers are 198,498,930,637,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,498,930,637,991 is 1608007491090.
Find LCM of 198,498,930,637,991 with Prime Factorization
| 2 | 198, 498, 930, 637, 991 |
| 3 | 99, 249, 465, 637, 991 |
| 33, 83, 155, 637, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 33 x 83 x 155 x 637 x 991 = 1608007491090
Therefore, the lowest common multiple of 198,498,930,637,991 is 1608007491090.
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.
198 x 498 x 930 x 637 x 991 = 57888269679240
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
498 : 1, 2, 3, 6, 83, 166, 249, 498
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
637 : 1, 7, 13, 49, 91, 637
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,498,930,637,991, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
498:2x 3x 83
930:2x 3x 5x 31
637:7x 7x 13
991:991
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 3 = 36
Therefore, the value for common factors is 36.
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 = 57888269679240/(1x36)
LCM = 57888269679240/36
LCM = 1608007491090
Thus, we can understand that the LCM of 198,498,930,637,991 is 1608007491090.
