Given numbers are 916,486,390,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,486,390,650 is 72341100.
Find LCM of 916,486,390,650 with Prime Factorization
2 | 916, 486, 390, 650 |
3 | 458, 243, 195, 325 |
5 | 458, 81, 65, 325 |
13 | 458, 81, 13, 65 |
458, 81, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 458 x 81 x 1 x 5 = 72341100
Therefore, the lowest common multiple of 916,486,390,650 is 72341100.
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.
916 x 486 x 390 x 650 = 112852116000
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.
916 : 1, 2, 4, 229, 458, 916
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,486,390,650, is 2.
Now, the common factors can be found like this.
916:2x 2x 229
486:2x 3x 3x 3x 3x 3
390:2x 3x 5x 13
650:2x 5x 5x 13
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 13 = 780
Therefore, the value for common factors is 780.
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 = 112852116000/(2x780)
LCM = 112852116000/1560
LCM = 72341100
Thus, we can understand that the LCM of 916,486,390,650 is 72341100.
