Given numbers are 930,734,711,646,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,734,711,646,721 is 18838015325010.
Find LCM of 930,734,711,646,721 with Prime Factorization
| 2 | 930, 734, 711, 646, 721 |
| 3 | 465, 367, 711, 323, 721 |
| 155, 367, 237, 323, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 155 x 367 x 237 x 323 x 721 = 18838015325010
Therefore, the lowest common multiple of 930,734,711,646,721 is 18838015325010.
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.
930 x 734 x 711 x 646 x 721 = 226056183900120
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
734 : 1, 2, 367, 734
711 : 1, 3, 9, 79, 237, 711
646 : 1, 2, 17, 19, 34, 38, 323, 646
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,734,711,646,721, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
734:2x 367
711:3x 3x 79
646:2x 17x 19
721:7x 103
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 3 = 12
Therefore, the value for common factors is 12.
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 = 226056183900120/(1x12)
LCM = 226056183900120/12
LCM = 18838015325010
Thus, we can understand that the LCM of 930,734,711,646,721 is 18838015325010.
