Given numbers are 74,28,48,28,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 74,28,48,28,102 is 211344.
Find LCM of 74,28,48,28,102 with Prime Factorization
| 2 | 74, 28, 48, 28, 102 |
| 2 | 37, 14, 24, 14, 51 |
| 3 | 37, 7, 12, 7, 51 |
| 7 | 37, 7, 4, 7, 17 |
| 37, 1, 4, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 37 x 1 x 4 x 1 x 17 = 211344
Therefore, the lowest common multiple of 74,28,48,28,102 is 211344.
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.
74 x 28 x 48 x 28 x 102 = 284046336
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.
74 : 1, 2, 37, 74
28 : 1, 2, 4, 7, 14, 28
48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
28 : 1, 2, 4, 7, 14, 28
102 : 1, 2, 3, 6, 17, 34, 51, 102
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 74,28,48,28,102, is 2.
Now, the common factors can be found like this.
74:2x 37
28:2x 2x 7
48:2x 2x 2x 2x 3
28:2x 2x 7
102:2x 3x 17
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 2x 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 284046336/(2x672)
LCM = 284046336/1344
LCM = 211344
Thus, we can understand that the LCM of 74,28,48,28,102 is 211344.
