Given numbers are 87,84,98,28,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 87,84,98,28,271 is 4621092.
Find LCM of 87,84,98,28,271 with Prime Factorization
2 | 87, 84, 98, 28, 271 |
2 | 87, 42, 49, 14, 271 |
3 | 87, 21, 49, 7, 271 |
7 | 29, 7, 49, 7, 271 |
29, 1, 1, 7, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 1 x 1 x 7 x 271 = 4621092
Therefore, the lowest common multiple of 87,84,98,28,271 is 4621092.
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.
87 x 84 x 98 x 28 x 271 = 5434404192
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.
87 : 1, 3, 29, 87
84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
98 : 1, 2, 7, 14, 49, 98
28 : 1, 2, 4, 7, 14, 28
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 87,84,98,28,271, is 1.
Now, the common factors can be found like this.
87:3x 29
84:2x 2x 3x 7
98:2x 7x 7
28:2x 2x 7
271:271
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 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 5434404192/(1x1176)
LCM = 5434404192/1176
LCM = 4621092
Thus, we can understand that the LCM of 87,84,98,28,271 is 4621092.
