Given numbers are 711,481,650,660,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,481,650,660,421 is 158376032100.
Find LCM of 711,481,650,660,421 with Prime Factorization
| 2 | 711, 481, 650, 660, 421 |
| 3 | 711, 481, 325, 330, 421 |
| 5 | 237, 481, 325, 110, 421 |
| 13 | 237, 481, 65, 22, 421 |
| 237, 37, 5, 22, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 237 x 37 x 5 x 22 x 421 = 158376032100
Therefore, the lowest common multiple of 711,481,650,660,421 is 158376032100.
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.
711 x 481 x 650 x 660 x 421 = 61766652519000
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.
711 : 1, 3, 9, 79, 237, 711
481 : 1, 13, 37, 481
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,481,650,660,421, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
481:13x 37
650:2x 5x 5x 13
660:2x 2x 3x 5x 11
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 61766652519000/(1x390)
LCM = 61766652519000/390
LCM = 158376032100
Thus, we can understand that the LCM of 711,481,650,660,421 is 158376032100.
