Find LCM of 443,473,136,872,989 with Prime Factorization
2 | 443, 473, 136, 872, 989 |
2 | 443, 473, 68, 436, 989 |
2 | 443, 473, 34, 218, 989 |
43 | 443, 473, 17, 109, 989 |
443, 11, 17, 109, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 43 x 443 x 11 x 17 x 109 x 23 = 71442741128
Therefore, the lowest common multiple of 443,473,136,872,989 is 71442741128.
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.
443 x 473 x 136 x 872 x 989 = 24576302948032
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.
443 : 1, 443
473 : 1, 11, 43, 473
136 : 1, 2, 4, 8, 17, 34, 68, 136
872 : 1, 2, 4, 8, 109, 218, 436, 872
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,473,136,872,989, is 1.
Now, the common factors can be found like this.
443:443
473:11x 43
136:2x 2x 2x 17
872:2x 2x 2x 109
989:23x 43
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 2x 43 = 344
Therefore, the value for common factors is 344.
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 = 24576302948032/(1x344)
LCM = 24576302948032/344
LCM = 71442741128
Thus, we can understand that the LCM of 443,473,136,872,989 is 71442741128.
