Find LCM of 749,646,450,900 with Prime Factorization
2 | 749, 646, 450, 900 |
3 | 749, 323, 225, 450 |
3 | 749, 323, 75, 150 |
5 | 749, 323, 25, 50 |
5 | 749, 323, 5, 10 |
749, 323, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 5 x 749 x 323 x 1 x 2 = 217734300
Therefore, the lowest common multiple of 749,646,450,900 is 217734300.
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 646 x 450 x 900 = 195960870000
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,646,450,900, is 1.
Now, the common factors can be found like this.
749:7x 107
646:2x 17x 19
450:2x 3x 3x 5x 5
900:2x 2x 3x 3x 5x 5
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 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 195960870000/(1x900)
LCM = 195960870000/900
LCM = 217734300
Thus, we can understand that the LCM of 749,646,450,900 is 217734300.
