Given numbers are 605,421,787,230
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,421,787,230 is 9220830410.
Find LCM of 605,421,787,230 with Prime Factorization
| 5 | 605, 421, 787, 230 |
| 121, 421, 787, 46 |
Multiply the prime numbers at the bottom and the left side.
5 x 121 x 421 x 787 x 46 = 9220830410
Therefore, the lowest common multiple of 605,421,787,230 is 9220830410.
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.
605 x 421 x 787 x 230 = 46104152050
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.
605 : 1, 5, 11, 55, 121, 605
421 : 1, 421
787 : 1, 787
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,421,787,230, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
421:421
787:787
230:2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 46104152050/(1x5)
LCM = 46104152050/5
LCM = 9220830410
Thus, we can understand that the LCM of 605,421,787,230 is 9220830410.
