Given numbers are 990,533,788,851,219
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,533,788,851,219 is 12915494703540.
Find LCM of 990,533,788,851,219 with Prime Factorization
| 2 | 990, 533, 788, 851, 219 |
| 3 | 495, 533, 394, 851, 219 |
| 165, 533, 394, 851, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 165 x 533 x 394 x 851 x 73 = 12915494703540
Therefore, the lowest common multiple of 990,533,788,851,219 is 12915494703540.
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 533 x 788 x 851 x 219 = 77492968221240
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
533 : 1, 13, 41, 533
788 : 1, 2, 4, 197, 394, 788
851 : 1, 23, 37, 851
219 : 1, 3, 73, 219
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,533,788,851,219, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
533:13x 41
788:2x 2x 197
851:23x 37
219:3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 77492968221240/(1x6)
LCM = 77492968221240/6
LCM = 12915494703540
Thus, we can understand that the LCM of 990,533,788,851,219 is 12915494703540.
