Given numbers are 165,650,911,442,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,650,911,442,542 is 90025156650.
Find LCM of 165,650,911,442,542 with Prime Factorization
| 2 | 165, 650, 911, 442, 542 |
| 5 | 165, 325, 911, 221, 271 |
| 13 | 33, 65, 911, 221, 271 |
| 33, 5, 911, 17, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 33 x 5 x 911 x 17 x 271 = 90025156650
Therefore, the lowest common multiple of 165,650,911,442,542 is 90025156650.
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.
165 x 650 x 911 x 442 x 542 = 23406540729000
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
911 : 1, 911
442 : 1, 2, 13, 17, 26, 34, 221, 442
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,650,911,442,542, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
650:2x 5x 5x 13
911:911
442:2x 13x 17
542:2x 271
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 23406540729000/(1x260)
LCM = 23406540729000/260
LCM = 90025156650
Thus, we can understand that the LCM of 165,650,911,442,542 is 90025156650.
