Given numbers are 668,301,385,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,301,385,746 is 4124910020.
Find LCM of 668,301,385,746 with Prime Factorization
| 2 | 668, 301, 385, 746 |
| 7 | 334, 301, 385, 373 |
| 334, 43, 55, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 334 x 43 x 55 x 373 = 4124910020
Therefore, the lowest common multiple of 668,301,385,746 is 4124910020.
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.
668 x 301 x 385 x 746 = 57748740280
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.
668 : 1, 2, 4, 167, 334, 668
301 : 1, 7, 43, 301
385 : 1, 5, 7, 11, 35, 55, 77, 385
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,301,385,746, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
301:7x 43
385:5x 7x 11
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 57748740280/(1x14)
LCM = 57748740280/14
LCM = 4124910020
Thus, we can understand that the LCM of 668,301,385,746 is 4124910020.
