Given numbers are 970,645,988,238,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,645,988,238,860 is 7355892180.
Find LCM of 970,645,988,238,860 with Prime Factorization
| 2 | 970, 645, 988, 238, 860 |
| 2 | 485, 645, 494, 119, 430 |
| 5 | 485, 645, 247, 119, 215 |
| 43 | 97, 129, 247, 119, 43 |
| 97, 3, 247, 119, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 97 x 3 x 247 x 119 x 1 = 7355892180
Therefore, the lowest common multiple of 970,645,988,238,860 is 7355892180.
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.
970 x 645 x 988 x 238 x 860 = 126521345496000
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
645 : 1, 3, 5, 15, 43, 129, 215, 645
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
238 : 1, 2, 7, 14, 17, 34, 119, 238
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,645,988,238,860, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
645:3x 5x 43
988:2x 2x 13x 19
238:2x 7x 17
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 5x 43 = 17200
Therefore, the value for common factors is 17200.
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 = 126521345496000/(1x17200)
LCM = 126521345496000/17200
LCM = 7355892180
Thus, we can understand that the LCM of 970,645,988,238,860 is 7355892180.
