Given numbers are 513,421,802,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,421,802,128 is 11085462144.
Find LCM of 513,421,802,128 with Prime Factorization
2 | 513, 421, 802, 128 |
513, 421, 401, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 513 x 421 x 401 x 64 = 11085462144
Therefore, the lowest common multiple of 513,421,802,128 is 11085462144.
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.
513 x 421 x 802 x 128 = 22170924288
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
421 : 1, 421
802 : 1, 2, 401, 802
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,421,802,128, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
421:421
802:2x 401
128:2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 22170924288/(1x2)
LCM = 22170924288/2
LCM = 11085462144
Thus, we can understand that the LCM of 513,421,802,128 is 11085462144.
