Given numbers are 304,621,245,209,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,621,245,209,938 is 34087782960.
Find LCM of 304,621,245,209,938 with Prime Factorization
| 2 | 304, 621, 245, 209, 938 |
| 7 | 152, 621, 245, 209, 469 |
| 19 | 152, 621, 35, 209, 67 |
| 8, 621, 35, 11, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 8 x 621 x 35 x 11 x 67 = 34087782960
Therefore, the lowest common multiple of 304,621,245,209,938 is 34087782960.
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.
304 x 621 x 245 x 209 x 938 = 9067350267360
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
621 : 1, 3, 9, 23, 27, 69, 207, 621
245 : 1, 5, 7, 35, 49, 245
209 : 1, 11, 19, 209
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,621,245,209,938, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
621:3x 3x 3x 23
245:5x 7x 7
209:11x 19
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 9067350267360/(1x266)
LCM = 9067350267360/266
LCM = 34087782960
Thus, we can understand that the LCM of 304,621,245,209,938 is 34087782960.
