Given numbers are 850,721,408,214,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,721,408,214,749 is 786899400.
Find LCM of 850,721,408,214,749 with Prime Factorization
| 2 | 850, 721, 408, 214, 749 |
| 7 | 425, 721, 204, 107, 749 |
| 17 | 425, 103, 204, 107, 107 |
| 107 | 25, 103, 12, 107, 107 |
| 25, 103, 12, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 107 x 25 x 103 x 12 x 1 x 1 = 786899400
Therefore, the lowest common multiple of 850,721,408,214,749 is 786899400.
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.
850 x 721 x 408 x 214 x 749 = 40078360240800
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
721 : 1, 7, 103, 721
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
214 : 1, 2, 107, 214
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,721,408,214,749, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
721:7x 103
408:2x 2x 2x 3x 17
214:2x 107
749:7x 107
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 7x 17x 107 = 50932
Therefore, the value for common factors is 50932.
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 = 40078360240800/(1x50932)
LCM = 40078360240800/50932
LCM = 786899400
Thus, we can understand that the LCM of 850,721,408,214,749 is 786899400.
