Given numbers are 662,971,203,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,971,203,945 is 17615988810.
Find LCM of 662,971,203,945 with Prime Factorization
| 7 | 662, 971, 203, 945 |
| 662, 971, 29, 135 |
Multiply the prime numbers at the bottom and the left side.
7 x 662 x 971 x 29 x 135 = 17615988810
Therefore, the lowest common multiple of 662,971,203,945 is 17615988810.
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.
662 x 971 x 203 x 945 = 123311921670
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.
662 : 1, 2, 331, 662
971 : 1, 971
203 : 1, 7, 29, 203
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,971,203,945, is 1.
Now, the common factors can be found like this.
662:2x 331
971:971
203:7x 29
945:3x 3x 3x 5x 7
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 = 123311921670/(1x7)
LCM = 123311921670/7
LCM = 17615988810
Thus, we can understand that the LCM of 662,971,203,945 is 17615988810.
