Given numbers are 989,399,611,480
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,399,611,480 is 38577171360.
Find LCM of 989,399,611,480 with Prime Factorization
| 3 | 989, 399, 611, 480 |
| 989, 133, 611, 160 |
Multiply the prime numbers at the bottom and the left side.
3 x 989 x 133 x 611 x 160 = 38577171360
Therefore, the lowest common multiple of 989,399,611,480 is 38577171360.
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.
989 x 399 x 611 x 480 = 115731514080
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.
989 : 1, 23, 43, 989
399 : 1, 3, 7, 19, 21, 57, 133, 399
611 : 1, 13, 47, 611
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,399,611,480, is 1.
Now, the common factors can be found like this.
989:23x 43
399:3x 7x 19
611:13x 47
480:2x 2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 115731514080/(1x3)
LCM = 115731514080/3
LCM = 38577171360
Thus, we can understand that the LCM of 989,399,611,480 is 38577171360.
