Given numbers are 399,698,768,302
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,698,768,302 is 5382886656.
Find LCM of 399,698,768,302 with Prime Factorization
| 2 | 399, 698, 768, 302 |
| 3 | 399, 349, 384, 151 |
| 133, 349, 128, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 133 x 349 x 128 x 151 = 5382886656
Therefore, the lowest common multiple of 399,698,768,302 is 5382886656.
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.
399 x 698 x 768 x 302 = 64594639872
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
698 : 1, 2, 349, 698
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
302 : 1, 2, 151, 302
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,698,768,302, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
698:2x 349
768:2x 2x 2x 2x 2x 2x 2x 2x 3
302:2x 151
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 3 = 12
Therefore, the value for common factors is 12.
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 = 64594639872/(1x12)
LCM = 64594639872/12
LCM = 5382886656
Thus, we can understand that the LCM of 399,698,768,302 is 5382886656.
