Find LCM of 716,821,990,330,321 with Prime Factorization
2 | 716, 821, 990, 330, 321 |
3 | 358, 821, 495, 165, 321 |
5 | 358, 821, 55, 165, 107 |
11 | 358, 821, 11, 33, 107 |
358, 821, 1, 3, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 358 x 821 x 1 x 3 x 107 = 31134733740
Therefore, the lowest common multiple of 716,821,990,330,321 is 31134733740.
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.
716 x 821 x 990 x 330 x 321 = 61646772805200
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.
716 : 1, 2, 4, 179, 358, 716
821 : 1, 821
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
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,821,990,330,321, is 1.
Now, the common factors can be found like this.
716:2x 2x 179
821:821
990:2x 3x 3x 5x 11
330:2x 3x 5x 11
321:3x 107
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 3x 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 61646772805200/(1x1980)
LCM = 61646772805200/1980
LCM = 31134733740
Thus, we can understand that the LCM of 716,821,990,330,321 is 31134733740.
