Given numbers are 735,715,457,851,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 735,715,457,851,621 is 367884632115.
Find LCM of 735,715,457,851,621 with Prime Factorization
| 3 | 735, 715, 457, 851, 621 |
| 5 | 245, 715, 457, 851, 207 |
| 23 | 49, 143, 457, 851, 207 |
| 49, 143, 457, 37, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 49 x 143 x 457 x 37 x 9 = 367884632115
Therefore, the lowest common multiple of 735,715,457,851,621 is 367884632115.
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.
735 x 715 x 457 x 851 x 621 = 126920198079675
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
715 : 1, 5, 11, 13, 55, 65, 143, 715
457 : 1, 457
851 : 1, 23, 37, 851
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,715,457,851,621, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
715:5x 11x 13
457:457
851:23x 37
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 126920198079675/(1x345)
LCM = 126920198079675/345
LCM = 367884632115
Thus, we can understand that the LCM of 735,715,457,851,621 is 367884632115.
