Find LCM of 443,972,738,399,644 with Prime Factorization
2 | 443, 972, 738, 399, 644 |
2 | 443, 486, 369, 399, 322 |
3 | 443, 243, 369, 399, 161 |
3 | 443, 81, 123, 133, 161 |
7 | 443, 27, 41, 133, 161 |
443, 27, 41, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 443 x 27 x 41 x 19 x 23 = 54004919724
Therefore, the lowest common multiple of 443,972,738,399,644 is 54004919724.
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 972 x 738 x 399 x 644 = 81655438622688
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
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
399 : 1, 3, 7, 19, 21, 57, 133, 399
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,972,738,399,644, is 1.
Now, the common factors can be found like this.
443:443
972:2x 2x 3x 3x 3x 3x 3
738:2x 3x 3x 41
399:3x 7x 19
644:2x 2x 7x 23
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 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 81655438622688/(1x1512)
LCM = 81655438622688/1512
LCM = 54004919724
Thus, we can understand that the LCM of 443,972,738,399,644 is 54004919724.
