Given numbers are 64,63,69,43,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 64,63,69,43,553 is 315024192.
Find LCM of 64,63,69,43,553 with Prime Factorization
| 3 | 64, 63, 69, 43, 553 |
| 7 | 64, 21, 23, 43, 553 |
| 64, 3, 23, 43, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 64 x 3 x 23 x 43 x 79 = 315024192
Therefore, the lowest common multiple of 64,63,69,43,553 is 315024192.
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.
64 x 63 x 69 x 43 x 553 = 6615508032
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.
64 : 1, 2, 4, 8, 16, 32, 64
63 : 1, 3, 7, 9, 21, 63
69 : 1, 3, 23, 69
43 : 1, 43
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 64,63,69,43,553, is 1.
Now, the common factors can be found like this.
64:2x 2x 2x 2x 2x 2
63:3x 3x 7
69:3x 23
43:43
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 6615508032/(1x21)
LCM = 6615508032/21
LCM = 315024192
Thus, we can understand that the LCM of 64,63,69,43,553 is 315024192.
