Given numbers are 681,355,739,838,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,355,739,838,770 is 11528018033070.
Find LCM of 681,355,739,838,770 with Prime Factorization
| 2 | 681, 355, 739, 838, 770 |
| 5 | 681, 355, 739, 419, 385 |
| 681, 71, 739, 419, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 681 x 71 x 739 x 419 x 77 = 11528018033070
Therefore, the lowest common multiple of 681,355,739,838,770 is 11528018033070.
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.
681 x 355 x 739 x 838 x 770 = 115280180330700
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.
681 : 1, 3, 227, 681
355 : 1, 5, 71, 355
739 : 1, 739
838 : 1, 2, 419, 838
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,355,739,838,770, is 1.
Now, the common factors can be found like this.
681:3x 227
355:5x 71
739:739
838:2x 419
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 115280180330700/(1x10)
LCM = 115280180330700/10
LCM = 11528018033070
Thus, we can understand that the LCM of 681,355,739,838,770 is 11528018033070.
