Given numbers are 750,250,162,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 750,250,162,490 is 992250.
Find LCM of 750,250,162,490 with Prime Factorization
| 2 | 750, 250, 162, 490 |
| 3 | 375, 125, 81, 245 |
| 5 | 125, 125, 27, 245 |
| 5 | 25, 25, 27, 49 |
| 5 | 5, 5, 27, 49 |
| 1, 1, 27, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 5 x 1 x 1 x 27 x 49 = 992250
Therefore, the lowest common multiple of 750,250,162,490 is 992250.
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.
750 x 250 x 162 x 490 = 14883750000
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.
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
250 : 1, 2, 5, 10, 25, 50, 125, 250
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,250,162,490, is 2.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
250:2x 5x 5x 5
162:2x 3x 3x 3x 3
490:2x 5x 7x 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 2x 3x 5x 5x 5x 5 = 7500
Therefore, the value for common factors is 7500.
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 = 14883750000/(2x7500)
LCM = 14883750000/15000
LCM = 992250
Thus, we can understand that the LCM of 750,250,162,490 is 992250.
