Find LCM of 893,642,147,882 with Prime Factorization
| 2 | 893, 642, 147, 882 |
| 3 | 893, 321, 147, 441 |
| 7 | 893, 107, 49, 147 |
| 7 | 893, 107, 7, 21 |
| 893, 107, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 893 x 107 x 1 x 3 = 84275982
Therefore, the lowest common multiple of 893,642,147,882 is 84275982.
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.
893 x 642 x 147 x 882 = 74331416124
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.
893 : 1, 19, 47, 893
642 : 1, 2, 3, 6, 107, 214, 321, 642
147 : 1, 3, 7, 21, 49, 147
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,642,147,882, is 1.
Now, the common factors can be found like this.
893:19x 47
642:2x 3x 107
147:3x 7x 7
882:2x 3x 3x 7x 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 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 74331416124/(1x882)
LCM = 74331416124/882
LCM = 84275982
Thus, we can understand that the LCM of 893,642,147,882 is 84275982.
