Find LCM of 101,320,960,921 with Prime Factorization
2 | 101, 320, 960, 921 |
2 | 101, 160, 480, 921 |
2 | 101, 80, 240, 921 |
2 | 101, 40, 120, 921 |
2 | 101, 20, 60, 921 |
2 | 101, 10, 30, 921 |
3 | 101, 5, 15, 921 |
5 | 101, 5, 5, 307 |
101, 1, 1, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 101 x 1 x 1 x 307 = 29766720
Therefore, the lowest common multiple of 101,320,960,921 is 29766720.
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.
101 x 320 x 960 x 921 = 28576051200
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.
101 : 1, 101
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,320,960,921, is 1.
Now, the common factors can be found like this.
101:101
320:2x 2x 2x 2x 2x 2x 5
960:2x 2x 2x 2x 2x 2x 3x 5
921:3x 307
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 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 28576051200/(1x960)
LCM = 28576051200/960
LCM = 29766720
Thus, we can understand that the LCM of 101,320,960,921 is 29766720.
