Given numbers are 659,990,391,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 659,990,391,685 is 34947646470.
Find LCM of 659,990,391,685 with Prime Factorization
5 | 659, 990, 391, 685 |
659, 198, 391, 137 |
Multiply the prime numbers at the bottom and the left side.
5 x 659 x 198 x 391 x 137 = 34947646470
Therefore, the lowest common multiple of 659,990,391,685 is 34947646470.
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.
659 x 990 x 391 x 685 = 174738232350
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.
659 : 1, 659
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
391 : 1, 17, 23, 391
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 659,990,391,685, is 1.
Now, the common factors can be found like this.
659:659
990:2x 3x 3x 5x 11
391:17x 23
685:5x 137
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 = 174738232350/(1x5)
LCM = 174738232350/5
LCM = 34947646470
Thus, we can understand that the LCM of 659,990,391,685 is 34947646470.
