Given numbers are 157,986,149,703,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,986,149,703,644 is 5221244520268.
Find LCM of 157,986,149,703,644 with Prime Factorization
| 2 | 157, 986, 149, 703, 644 |
| 157, 493, 149, 703, 322 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 493 x 149 x 703 x 322 = 5221244520268
Therefore, the lowest common multiple of 157,986,149,703,644 is 5221244520268.
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.
157 x 986 x 149 x 703 x 644 = 10442489040536
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.
157 : 1, 157
986 : 1, 2, 17, 29, 34, 58, 493, 986
149 : 1, 149
703 : 1, 19, 37, 703
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,986,149,703,644, is 1.
Now, the common factors can be found like this.
157:157
986:2x 17x 29
149:149
703:19x 37
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 10442489040536/(1x2)
LCM = 10442489040536/2
LCM = 5221244520268
Thus, we can understand that the LCM of 157,986,149,703,644 is 5221244520268.
