Given numbers are 251,121,781,986,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,121,781,986,279 is 593196471054.
Find LCM of 251,121,781,986,279 with Prime Factorization
| 11 | 251, 121, 781, 986, 279 |
| 251, 11, 71, 986, 279 |
Multiply the prime numbers at the bottom and the left side.
11 x 251 x 11 x 71 x 986 x 279 = 593196471054
Therefore, the lowest common multiple of 251,121,781,986,279 is 593196471054.
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.
251 x 121 x 781 x 986 x 279 = 6525161181594
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.
251 : 1, 251
121 : 1, 11, 121
781 : 1, 11, 71, 781
986 : 1, 2, 17, 29, 34, 58, 493, 986
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,121,781,986,279, is 1.
Now, the common factors can be found like this.
251:251
121:11x 11
781:11x 71
986:2x 17x 29
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 6525161181594/(1x11)
LCM = 6525161181594/11
LCM = 593196471054
Thus, we can understand that the LCM of 251,121,781,986,279 is 593196471054.
