Given numbers are 75,14,35,700
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 75,14,35,700 is 2100.
Find LCM of 75,14,35,700 with Prime Factorization
| 2 | 75, 14, 35, 700 |
| 5 | 75, 7, 35, 350 |
| 5 | 15, 7, 7, 70 |
| 7 | 3, 7, 7, 14 |
| 3, 1, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 7 x 3 x 1 x 1 x 2 = 2100
Therefore, the lowest common multiple of 75,14,35,700 is 2100.
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.
75 x 14 x 35 x 700 = 25725000
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.
75 : 1, 3, 5, 15, 25, 75
14 : 1, 2, 7, 14
35 : 1, 5, 7, 35
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 75,14,35,700, is 1.
Now, the common factors can be found like this.
75:3x 5x 5
14:2x 7
35:5x 7
700:2x 2x 5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 7x 7 = 12250
Therefore, the value for common factors is 12250.
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 = 25725000/(1x12250)
LCM = 25725000/12250
LCM = 2100
Thus, we can understand that the LCM of 75,14,35,700 is 2100.
