Find LCM of 855,283,965,390,772 with Prime Factorization
| 2 | 855, 283, 965, 390, 772 |
| 3 | 855, 283, 965, 195, 386 |
| 5 | 285, 283, 965, 65, 386 |
| 193 | 57, 283, 193, 13, 386 |
| 57, 283, 1, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 193 x 57 x 283 x 1 x 13 x 2 = 2428360740
Therefore, the lowest common multiple of 855,283,965,390,772 is 2428360740.
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.
855 x 283 x 965 x 390 x 772 = 70301043423000
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
283 : 1, 283
965 : 1, 5, 193, 965
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,283,965,390,772, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
283:283
965:5x 193
390:2x 3x 5x 13
772:2x 2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 193 = 28950
Therefore, the value for common factors is 28950.
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 = 70301043423000/(1x28950)
LCM = 70301043423000/28950
LCM = 2428360740
Thus, we can understand that the LCM of 855,283,965,390,772 is 2428360740.
