Given numbers are 939,438,242,228,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,438,242,228,421 is 265380807252.
Find LCM of 939,438,242,228,421 with Prime Factorization
| 2 | 939, 438, 242, 228, 421 |
| 3 | 939, 219, 121, 114, 421 |
| 313, 73, 121, 38, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 313 x 73 x 121 x 38 x 421 = 265380807252
Therefore, the lowest common multiple of 939,438,242,228,421 is 265380807252.
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.
939 x 438 x 242 x 228 x 421 = 9553709061072
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.
939 : 1, 3, 313, 939
438 : 1, 2, 3, 6, 73, 146, 219, 438
242 : 1, 2, 11, 22, 121, 242
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,438,242,228,421, is 1.
Now, the common factors can be found like this.
939:3x 313
438:2x 3x 73
242:2x 11x 11
228:2x 2x 3x 19
421:421
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 9553709061072/(1x36)
LCM = 9553709061072/36
LCM = 265380807252
Thus, we can understand that the LCM of 939,438,242,228,421 is 265380807252.
