Given numbers are 755,988,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,988,970 is 72356180.
Find LCM of 755,988,970 with Prime Factorization
| 2 | 755, 988, 970 |
| 5 | 755, 494, 485 |
| 151, 494, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 151 x 494 x 97 = 72356180
Therefore, the lowest common multiple of 755,988,970 is 72356180.
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.
755 x 988 x 970 = 723561800
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.
755 : 1, 5, 151, 755
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,988,970, is 1.
Now, the common factors can be found like this.
755:5x 151
988:2x 2x 13x 19
970:2x 5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 723561800/(1x10)
LCM = 723561800/10
LCM = 72356180
Thus, we can understand that the LCM of 755,988,970 is 72356180.
