Given numbers are 835,718,280,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 835,718,280,392 is 117507880.
Find LCM of 835,718,280,392 with Prime Factorization
2 | 835, 718, 280, 392 |
2 | 835, 359, 140, 196 |
2 | 835, 359, 70, 98 |
5 | 835, 359, 35, 49 |
7 | 167, 359, 7, 49 |
167, 359, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 167 x 359 x 1 x 7 = 117507880
Therefore, the lowest common multiple of 835,718,280,392 is 117507880.
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.
835 x 718 x 280 x 392 = 65804412800
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.
835 : 1, 5, 167, 835
718 : 1, 2, 359, 718
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,718,280,392, is 1.
Now, the common factors can be found like this.
835:5x 167
718:2x 359
280:2x 2x 2x 5x 7
392:2x 2x 2x 7x 7
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 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 65804412800/(1x560)
LCM = 65804412800/560
LCM = 117507880
Thus, we can understand that the LCM of 835,718,280,392 is 117507880.
