Given numbers are 307,921,956,820,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 307,921,956,820,461 is 83209384380.
Find LCM of 307,921,956,820,461 with Prime Factorization
| 2 | 307, 921, 956, 820, 461 |
| 2 | 307, 921, 478, 410, 461 |
| 307 | 307, 921, 239, 205, 461 |
| 1, 3, 239, 205, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 307 x 1 x 3 x 239 x 205 x 461 = 83209384380
Therefore, the lowest common multiple of 307,921,956,820,461 is 83209384380.
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.
307 x 921 x 956 x 820 x 461 = 102181124018640
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.
307 : 1, 307
921 : 1, 3, 307, 921
956 : 1, 2, 4, 239, 478, 956
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,921,956,820,461, is 1.
Now, the common factors can be found like this.
307:307
921:3x 307
956:2x 2x 239
820:2x 2x 5x 41
461:461
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 307 = 1228
Therefore, the value for common factors is 1228.
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 = 102181124018640/(1x1228)
LCM = 102181124018640/1228
LCM = 83209384380
Thus, we can understand that the LCM of 307,921,956,820,461 is 83209384380.
