Given numbers are 406,680,136,708
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,680,136,708 is 24433080.
Find LCM of 406,680,136,708 with Prime Factorization
| 2 | 406, 680, 136, 708 |
| 2 | 203, 340, 68, 354 |
| 2 | 203, 170, 34, 177 |
| 17 | 203, 85, 17, 177 |
| 203, 5, 1, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 203 x 5 x 1 x 177 = 24433080
Therefore, the lowest common multiple of 406,680,136,708 is 24433080.
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.
406 x 680 x 136 x 708 = 26583191040
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
136 : 1, 2, 4, 8, 17, 34, 68, 136
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,680,136,708, is 2.
Now, the common factors can be found like this.
406:2x 7x 29
680:2x 2x 2x 5x 17
136:2x 2x 2x 17
708:2x 2x 3x 59
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 2x 2x 17 = 544
Therefore, the value for common factors is 544.
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 = 26583191040/(2x544)
LCM = 26583191040/1088
LCM = 24433080
Thus, we can understand that the LCM of 406,680,136,708 is 24433080.
