Given numbers are 361,203,798,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,203,798,938 is 29459766.
Find LCM of 361,203,798,938 with Prime Factorization
| 2 | 361, 203, 798, 938 |
| 7 | 361, 203, 399, 469 |
| 19 | 361, 29, 57, 67 |
| 19, 29, 3, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 19 x 29 x 3 x 67 = 29459766
Therefore, the lowest common multiple of 361,203,798,938 is 29459766.
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.
361 x 203 x 798 x 938 = 54854084292
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.
361 : 1, 19, 361
203 : 1, 7, 29, 203
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
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 361,203,798,938, is 1.
Now, the common factors can be found like this.
361:19x 19
203:7x 29
798:2x 3x 7x 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 7x 19 = 1862
Therefore, the value for common factors is 1862.
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 = 54854084292/(1x1862)
LCM = 54854084292/1862
LCM = 29459766
Thus, we can understand that the LCM of 361,203,798,938 is 29459766.
