Find LCM of 770,385,959,216,972 with Prime Factorization
| 2 | 770, 385, 959, 216, 972 |
| 2 | 385, 385, 959, 108, 486 |
| 3 | 385, 385, 959, 54, 243 |
| 3 | 385, 385, 959, 18, 81 |
| 3 | 385, 385, 959, 6, 27 |
| 5 | 385, 385, 959, 2, 9 |
| 7 | 77, 77, 959, 2, 9 |
| 11 | 11, 11, 137, 2, 9 |
| 1, 1, 137, 2, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 7 x 11 x 1 x 1 x 137 x 2 x 9 = 102536280
Therefore, the lowest common multiple of 770,385,959,216,972 is 102536280.
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.
770 x 385 x 959 x 216 x 972 = 59688419313600
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
385 : 1, 5, 7, 11, 35, 55, 77, 385
959 : 1, 7, 137, 959
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,385,959,216,972, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
385:5x 7x 11
959:7x 137
216:2x 2x 2x 3x 3x 3
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3x 5x 7x 7x 11 = 582120
Therefore, the value for common factors is 582120.
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 = 59688419313600/(1x582120)
LCM = 59688419313600/582120
LCM = 102536280
Thus, we can understand that the LCM of 770,385,959,216,972 is 102536280.
