Find LCM of 334,420,665,447,791 with Prime Factorization
2 | 334, 420, 665, 447, 791 |
3 | 167, 210, 665, 447, 791 |
5 | 167, 70, 665, 149, 791 |
7 | 167, 14, 133, 149, 791 |
167, 2, 19, 149, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 167 x 2 x 19 x 149 x 113 = 22437996420
Therefore, the lowest common multiple of 334,420,665,447,791 is 22437996420.
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.
334 x 420 x 665 x 447 x 791 = 32983854737400
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.
334 : 1, 2, 167, 334
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
665 : 1, 5, 7, 19, 35, 95, 133, 665
447 : 1, 3, 149, 447
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 334,420,665,447,791, is 1.
Now, the common factors can be found like this.
334:2x 167
420:2x 2x 3x 5x 7
665:5x 7x 19
447:3x 149
791:7x 113
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 7x 7 = 1470
Therefore, the value for common factors is 1470.
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 = 32983854737400/(1x1470)
LCM = 32983854737400/1470
LCM = 22437996420
Thus, we can understand that the LCM of 334,420,665,447,791 is 22437996420.
