Given numbers are 347,605,870,621,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,605,870,621,681 is 1716446614410.
Find LCM of 347,605,870,621,681 with Prime Factorization
| 3 | 347, 605, 870, 621, 681 |
| 5 | 347, 605, 290, 207, 227 |
| 347, 121, 58, 207, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 347 x 121 x 58 x 207 x 227 = 1716446614410
Therefore, the lowest common multiple of 347,605,870,621,681 is 1716446614410.
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.
347 x 605 x 870 x 621 x 681 = 77240097648450
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.
347 : 1, 347
605 : 1, 5, 11, 55, 121, 605
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
621 : 1, 3, 9, 23, 27, 69, 207, 621
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,605,870,621,681, is 1.
Now, the common factors can be found like this.
347:347
605:5x 11x 11
870:2x 3x 5x 29
621:3x 3x 3x 23
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 77240097648450/(1x45)
LCM = 77240097648450/45
LCM = 1716446614410
Thus, we can understand that the LCM of 347,605,870,621,681 is 1716446614410.
