Given numbers are 51,75,63,30,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 51,75,63,30,994 is 3802050.
Find LCM of 51,75,63,30,994 with Prime Factorization
| 2 | 51, 75, 63, 30, 994 |
| 3 | 51, 75, 63, 15, 497 |
| 5 | 17, 25, 21, 5, 497 |
| 7 | 17, 1, 21, 5, 497 |
| 17, 1, 3, 5, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 17 x 1 x 3 x 5 x 71 = 3802050
Therefore, the lowest common multiple of 51,75,63,30,994 is 3802050.
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.
51 x 75 x 63 x 30 x 994 = 7185874500
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.
51 : 1, 3, 17, 51
75 : 1, 3, 5, 15, 25, 75
63 : 1, 3, 7, 9, 21, 63
30 : 1, 2, 3, 5, 6, 10, 15, 30
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 51,75,63,30,994, is 1.
Now, the common factors can be found like this.
51:3x 17
75:3x 5x 5
63:3x 3x 7
30:2x 3x 5
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 7 = 1890
Therefore, the value for common factors is 1890.
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 = 7185874500/(1x1890)
LCM = 7185874500/1890
LCM = 3802050
Thus, we can understand that the LCM of 51,75,63,30,994 is 3802050.
