Given numbers are 145,821,428,811,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 145,821,428,811,749 is 289250303020.
Find LCM of 145,821,428,811,749 with Prime Factorization
107 | 145, 821, 428, 811, 749 |
145, 821, 4, 811, 7 |
Multiply the prime numbers at the bottom and the left side.
107 x 145 x 821 x 4 x 811 x 7 = 289250303020
Therefore, the lowest common multiple of 145,821,428,811,749 is 289250303020.
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.
145 x 821 x 428 x 811 x 749 = 30949782423140
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.
145 : 1, 5, 29, 145
821 : 1, 821
428 : 1, 2, 4, 107, 214, 428
811 : 1, 811
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,821,428,811,749, is 1.
Now, the common factors can be found like this.
145:5x 29
821:821
428:2x 2x 107
811:811
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.
107 = 107
Therefore, the value for common factors is 107.
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 = 30949782423140/(1x107)
LCM = 30949782423140/107
LCM = 289250303020
Thus, we can understand that the LCM of 145,821,428,811,749 is 289250303020.
