Given numbers are 103,308,805,157
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,308,805,157 is 572776820.
Find LCM of 103,308,805,157 with Prime Factorization
| 7 | 103, 308, 805, 157 |
| 103, 44, 115, 157 |
Multiply the prime numbers at the bottom and the left side.
7 x 103 x 44 x 115 x 157 = 572776820
Therefore, the lowest common multiple of 103,308,805,157 is 572776820.
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.
103 x 308 x 805 x 157 = 4009437740
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.
103 : 1, 103
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
805 : 1, 5, 7, 23, 35, 115, 161, 805
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,308,805,157, is 1.
Now, the common factors can be found like this.
103:103
308:2x 2x 7x 11
805:5x 7x 23
157:157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 4009437740/(1x7)
LCM = 4009437740/7
LCM = 572776820
Thus, we can understand that the LCM of 103,308,805,157 is 572776820.
