Given numbers are 83,65,64,87,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 83,65,64,87,351 is 270354240.
Find LCM of 83,65,64,87,351 with Prime Factorization
3 | 83, 65, 64, 87, 351 |
13 | 83, 65, 64, 29, 117 |
83, 5, 64, 29, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 83 x 5 x 64 x 29 x 9 = 270354240
Therefore, the lowest common multiple of 83,65,64,87,351 is 270354240.
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.
83 x 65 x 64 x 87 x 351 = 10543815360
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.
83 : 1, 83
65 : 1, 5, 13, 65
64 : 1, 2, 4, 8, 16, 32, 64
87 : 1, 3, 29, 87
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 83,65,64,87,351, is 1.
Now, the common factors can be found like this.
83:83
65:5x 13
64:2x 2x 2x 2x 2x 2
87:3x 29
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 10543815360/(1x39)
LCM = 10543815360/39
LCM = 270354240
Thus, we can understand that the LCM of 83,65,64,87,351 is 270354240.
