Find LCM of 144,912,913,121,140 with Prime Factorization
| 2 | 144, 912, 913, 121, 140 |
| 2 | 72, 456, 913, 121, 70 |
| 2 | 36, 228, 913, 121, 35 |
| 2 | 18, 114, 913, 121, 35 |
| 3 | 9, 57, 913, 121, 35 |
| 11 | 3, 19, 913, 121, 35 |
| 3, 19, 83, 11, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 3 x 19 x 83 x 11 x 35 = 961717680
Therefore, the lowest common multiple of 144,912,913,121,140 is 961717680.
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.
144 x 912 x 913 x 121 x 140 = 2031147740160
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
913 : 1, 11, 83, 913
121 : 1, 11, 121
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,912,913,121,140, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
912:2x 2x 2x 2x 3x 19
913:11x 83
121:11x 11
140:2x 2x 5x 7
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 11 = 2112
Therefore, the value for common factors is 2112.
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 = 2031147740160/(1x2112)
LCM = 2031147740160/2112
LCM = 961717680
Thus, we can understand that the LCM of 144,912,913,121,140 is 961717680.
