Given numbers are 749,303,909,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,303,909,321 is 680841.
Find LCM of 749,303,909,321 with Prime Factorization
| 3 | 749, 303, 909, 321 |
| 101 | 749, 101, 303, 107 |
| 107 | 749, 1, 3, 107 |
| 7, 1, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 101 x 107 x 7 x 1 x 3 x 1 = 680841
Therefore, the lowest common multiple of 749,303,909,321 is 680841.
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.
749 x 303 x 909 x 321 = 66220638183
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.
749 : 1, 7, 107, 749
303 : 1, 3, 101, 303
909 : 1, 3, 9, 101, 303, 909
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,303,909,321, is 1.
Now, the common factors can be found like this.
749:7x 107
303:3x 101
909:3x 3x 101
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 101x 107 = 97263
Therefore, the value for common factors is 97263.
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 = 66220638183/(1x97263)
LCM = 66220638183/97263
LCM = 680841
Thus, we can understand that the LCM of 749,303,909,321 is 680841.
