Given numbers are 440,550,690,842,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,550,690,842,653 is 41731793400.
Find LCM of 440,550,690,842,653 with Prime Factorization
| 2 | 440, 550, 690, 842, 653 |
| 5 | 220, 275, 345, 421, 653 |
| 11 | 44, 55, 69, 421, 653 |
| 4, 5, 69, 421, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 4 x 5 x 69 x 421 x 653 = 41731793400
Therefore, the lowest common multiple of 440,550,690,842,653 is 41731793400.
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.
440 x 550 x 690 x 842 x 653 = 91809945480000
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
842 : 1, 2, 421, 842
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,550,690,842,653, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
550:2x 5x 5x 11
690:2x 3x 5x 23
842:2x 421
653:653
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 2x 5x 5x 11 = 2200
Therefore, the value for common factors is 2200.
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 = 91809945480000/(1x2200)
LCM = 91809945480000/2200
LCM = 41731793400
Thus, we can understand that the LCM of 440,550,690,842,653 is 41731793400.
