Given numbers are 418,505,650,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,505,650,165 is 41162550.
Find LCM of 418,505,650,165 with Prime Factorization
| 2 | 418, 505, 650, 165 |
| 5 | 209, 505, 325, 165 |
| 11 | 209, 101, 65, 33 |
| 19, 101, 65, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 101 x 65 x 3 = 41162550
Therefore, the lowest common multiple of 418,505,650,165 is 41162550.
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.
418 x 505 x 650 x 165 = 22639402500
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
505 : 1, 5, 101, 505
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,505,650,165, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
505:5x 101
650:2x 5x 5x 13
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11 = 550
Therefore, the value for common factors is 550.
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 = 22639402500/(1x550)
LCM = 22639402500/550
LCM = 41162550
Thus, we can understand that the LCM of 418,505,650,165 is 41162550.
