The LCM of 945,307,440,770 is 25530120.
Find LCM of 945,307,440,770 with Prime Factorization
2 | 945, 307, 440, 770 |
5 | 945, 307, 220, 385 |
7 | 189, 307, 44, 77 |
11 | 27, 307, 44, 11 |
27, 307, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 27 x 307 x 4 x 1 = 25530120
Therefore, the lowest common multiple of 945,307,440,770 is 25530120.
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.
945 x 307 x 440 x 770 = 98290962000
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
307 : 1, 307
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,307,440,770, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
307:307
440:2x 2x 2x 5x 11
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 11 = 3850
Therefore, the value for common factors is 3850.
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 = 98290962000/(1x3850)
LCM = 98290962000/3850
LCM = 25530120
Thus, we can understand that the LCM of 945,307,440,770 is 25530120.
