Find LCM of 342,147,665,378,374 with Prime Factorization
| 2 | 342, 147, 665, 378, 374 |
| 3 | 171, 147, 665, 189, 187 |
| 3 | 57, 49, 665, 63, 187 |
| 7 | 19, 49, 665, 21, 187 |
| 19 | 19, 7, 95, 3, 187 |
| 1, 7, 5, 3, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 19 x 1 x 7 x 5 x 3 x 187 = 47006190
Therefore, the lowest common multiple of 342,147,665,378,374 is 47006190.
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.
342 x 147 x 665 x 378 x 374 = 4726378392120
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
147 : 1, 3, 7, 21, 49, 147
665 : 1, 5, 7, 19, 35, 95, 133, 665
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,147,665,378,374, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
147:3x 7x 7
665:5x 7x 19
378:2x 3x 3x 3x 7
374:2x 11x 17
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 3x 3x 3x 7x 7x 19 = 100548
Therefore, the value for common factors is 100548.
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 = 4726378392120/(1x100548)
LCM = 4726378392120/100548
LCM = 47006190
Thus, we can understand that the LCM of 342,147,665,378,374 is 47006190.
