Given numbers are 668,706,306,670,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,706,306,670,355 is 858115515420.
Find LCM of 668,706,306,670,355 with Prime Factorization
| 2 | 668, 706, 306, 670, 355 |
| 5 | 334, 353, 153, 335, 355 |
| 334, 353, 153, 67, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 334 x 353 x 153 x 67 x 71 = 858115515420
Therefore, the lowest common multiple of 668,706,306,670,355 is 858115515420.
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 706 x 306 x 670 x 355 = 34324620616800
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
706 : 1, 2, 353, 706
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
670 : 1, 2, 5, 10, 67, 134, 335, 670
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,706,306,670,355, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
706:2x 353
306:2x 3x 3x 17
670:2x 5x 67
355:5x 71
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 5 = 40
Therefore, the value for common factors is 40.
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 = 34324620616800/(1x40)
LCM = 34324620616800/40
LCM = 858115515420
Thus, we can understand that the LCM of 668,706,306,670,355 is 858115515420.
