Given numbers are 721,188,218,733,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,188,218,733,930 is 5035893528540.
Find LCM of 721,188,218,733,930 with Prime Factorization
| 2 | 721, 188, 218, 733, 930 |
| 721, 94, 109, 733, 465 |
Multiply the prime numbers at the bottom and the left side.
2 x 721 x 94 x 109 x 733 x 465 = 5035893528540
Therefore, the lowest common multiple of 721,188,218,733,930 is 5035893528540.
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.
721 x 188 x 218 x 733 x 930 = 20143574114160
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.
721 : 1, 7, 103, 721
188 : 1, 2, 4, 47, 94, 188
218 : 1, 2, 109, 218
733 : 1, 733
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,188,218,733,930, is 1.
Now, the common factors can be found like this.
721:7x 103
188:2x 2x 47
218:2x 109
733:733
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 20143574114160/(1x4)
LCM = 20143574114160/4
LCM = 5035893528540
Thus, we can understand that the LCM of 721,188,218,733,930 is 5035893528540.
