Find LCM of 855,429,374,152,972 with Prime Factorization
| 2 | 855, 429, 374, 152, 972 |
| 2 | 855, 429, 187, 76, 486 |
| 3 | 855, 429, 187, 38, 243 |
| 3 | 285, 143, 187, 38, 81 |
| 11 | 95, 143, 187, 38, 27 |
| 19 | 95, 13, 17, 38, 27 |
| 5, 13, 17, 2, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 19 x 5 x 13 x 17 x 2 x 27 = 448957080
Therefore, the lowest common multiple of 855,429,374,152,972 is 448957080.
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 429 x 374 x 152 x 972 = 20267718419520
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
374 : 1, 2, 11, 17, 22, 34, 187, 374
152 : 1, 2, 4, 8, 19, 38, 76, 152
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 855,429,374,152,972, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
429:3x 11x 13
374:2x 11x 17
152:2x 2x 2x 19
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 11x 19 = 45144
Therefore, the value for common factors is 45144.
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 = 20267718419520/(1x45144)
LCM = 20267718419520/45144
LCM = 448957080
Thus, we can understand that the LCM of 855,429,374,152,972 is 448957080.
