Given numbers are 649,686,708,842,479
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,686,708,842,479 is 538688460156.
Find LCM of 649,686,708,842,479 with Prime Factorization
| 2 | 649, 686, 708, 842, 479 |
| 59 | 649, 343, 354, 421, 479 |
| 11, 343, 6, 421, 479 |
Multiply the prime numbers at the bottom and the left side.
2 x 59 x 11 x 343 x 6 x 421 x 479 = 538688460156
Therefore, the lowest common multiple of 649,686,708,842,479 is 538688460156.
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.
649 x 686 x 708 x 842 x 479 = 127130476596816
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.
649 : 1, 11, 59, 649
686 : 1, 2, 7, 14, 49, 98, 343, 686
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
842 : 1, 2, 421, 842
479 : 1, 479
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,686,708,842,479, is 1.
Now, the common factors can be found like this.
649:11x 59
686:2x 7x 7x 7
708:2x 2x 3x 59
842:2x 421
479:479
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 59 = 236
Therefore, the value for common factors is 236.
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 = 127130476596816/(1x236)
LCM = 127130476596816/236
LCM = 538688460156
Thus, we can understand that the LCM of 649,686,708,842,479 is 538688460156.
