Given numbers are 308,551,921,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,551,921,817 is 6720945924.
Find LCM of 308,551,921,817 with Prime Factorization
| 19 | 308, 551, 921, 817 |
| 308, 29, 921, 43 |
Multiply the prime numbers at the bottom and the left side.
19 x 308 x 29 x 921 x 43 = 6720945924
Therefore, the lowest common multiple of 308,551,921,817 is 6720945924.
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.
308 x 551 x 921 x 817 = 127697972556
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
551 : 1, 19, 29, 551
921 : 1, 3, 307, 921
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,551,921,817, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
551:19x 29
921:3x 307
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 127697972556/(1x19)
LCM = 127697972556/19
LCM = 6720945924
Thus, we can understand that the LCM of 308,551,921,817 is 6720945924.
