Find LCM of 300,428,686,745,298 with Prime Factorization
2 | 300, 428, 686, 745, 298 |
2 | 150, 214, 343, 745, 149 |
5 | 75, 107, 343, 745, 149 |
149 | 15, 107, 343, 149, 149 |
15, 107, 343, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 149 x 15 x 107 x 343 x 1 x 1 = 1640534700
Therefore, the lowest common multiple of 300,428,686,745,298 is 1640534700.
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.
300 x 428 x 686 x 745 x 298 = 19555173624000
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.
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
428 : 1, 2, 4, 107, 214, 428
686 : 1, 2, 7, 14, 49, 98, 343, 686
745 : 1, 5, 149, 745
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 300,428,686,745,298, is 1.
Now, the common factors can be found like this.
300:2x 2x 3x 5x 5
428:2x 2x 107
686:2x 7x 7x 7
745:5x 149
298:2x 149
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 2x 2x 5x 149 = 11920
Therefore, the value for common factors is 11920.
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 = 19555173624000/(1x11920)
LCM = 19555173624000/11920
LCM = 1640534700
Thus, we can understand that the LCM of 300,428,686,745,298 is 1640534700.
