Given numbers are 157,794,157,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,794,157,647 is 80653726.
Find LCM of 157,794,157,647 with Prime Factorization
| 157 | 157, 794, 157, 647 |
| 1, 794, 1, 647 |
Multiply the prime numbers at the bottom and the left side.
157 x 1 x 794 x 1 x 647 = 80653726
Therefore, the lowest common multiple of 157,794,157,647 is 80653726.
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 794 x 157 x 647 = 12662634982
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
794 : 1, 2, 397, 794
157 : 1, 157
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,794,157,647, is 1.
Now, the common factors can be found like this.
157:157
794:2x 397
157:157
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
157 = 157
Therefore, the value for common factors is 157.
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 = 12662634982/(1x157)
LCM = 12662634982/157
LCM = 80653726
Thus, we can understand that the LCM of 157,794,157,647 is 80653726.
