Given numbers are 781,330,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,330,525 is 820050.
Find LCM of 781,330,525 with Prime Factorization
| 3 | 781, 330, 525 |
| 5 | 781, 110, 175 |
| 11 | 781, 22, 35 |
| 71, 2, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 71 x 2 x 35 = 820050
Therefore, the lowest common multiple of 781,330,525 is 820050.
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.
781 x 330 x 525 = 135308250
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.
781 : 1, 11, 71, 781
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,330,525, is 1.
Now, the common factors can be found like this.
781:11x 71
330:2x 3x 5x 11
525:3x 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.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 135308250/(1x165)
LCM = 135308250/165
LCM = 820050
Thus, we can understand that the LCM of 781,330,525 is 820050.
