Given numbers are 249,996,157,691,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,996,157,691,655 is 70774749060.
Find LCM of 249,996,157,691,655 with Prime Factorization
| 3 | 249, 996, 157, 691, 655 |
| 83 | 83, 332, 157, 691, 655 |
| 1, 4, 157, 691, 655 |
Multiply the prime numbers at the bottom and the left side.
3 x 83 x 1 x 4 x 157 x 691 x 655 = 70774749060
Therefore, the lowest common multiple of 249,996,157,691,655 is 70774749060.
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.
249 x 996 x 157 x 691 x 655 = 17622912515940
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.
249 : 1, 3, 83, 249
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
157 : 1, 157
691 : 1, 691
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,996,157,691,655, is 1.
Now, the common factors can be found like this.
249:3x 83
996:2x 2x 3x 83
157:157
691:691
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 83 = 249
Therefore, the value for common factors is 249.
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 = 17622912515940/(1x249)
LCM = 17622912515940/249
LCM = 70774749060
Thus, we can understand that the LCM of 249,996,157,691,655 is 70774749060.
