Given numbers are 499,900,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 499,900,420 is 3143700.
Find LCM of 499,900,420 with Prime Factorization
| 2 | 499, 900, 420 |
| 2 | 499, 450, 210 |
| 3 | 499, 225, 105 |
| 5 | 499, 75, 35 |
| 499, 15, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 499 x 15 x 7 = 3143700
Therefore, the lowest common multiple of 499,900,420 is 3143700.
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.
499 x 900 x 420 = 188622000
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.
499 : 1, 499
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 499,900,420, is 1.
Now, the common factors can be found like this.
499:499
900:2x 2x 3x 3x 5x 5
420:2x 2x 3x 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 2x 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 188622000/(1x60)
LCM = 188622000/60
LCM = 3143700
Thus, we can understand that the LCM of 499,900,420 is 3143700.
