The LCM of 396,550,989,102 is 166448700.
Find LCM of 396,550,989,102 with Prime Factorization
| 2 | 396, 550, 989, 102 |
| 3 | 198, 275, 989, 51 |
| 11 | 66, 275, 989, 17 |
| 6, 25, 989, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 6 x 25 x 989 x 17 = 166448700
Therefore, the lowest common multiple of 396,550,989,102 is 166448700.
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.
396 x 550 x 989 x 102 = 21971228400
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
989 : 1, 23, 43, 989
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,550,989,102, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
550:2x 5x 5x 11
989:23x 43
102:2x 3x 17
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 11 = 132
Therefore, the value for common factors is 132.
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 = 21971228400/(1x132)
LCM = 21971228400/132
LCM = 166448700
Thus, we can understand that the LCM of 396,550,989,102 is 166448700.
