Given numbers are 634,815,535,705,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,815,535,705,910 is 709399943070.
Find LCM of 634,815,535,705,910 with Prime Factorization
| 2 | 634, 815, 535, 705, 910 |
| 5 | 317, 815, 535, 705, 455 |
| 317, 163, 107, 141, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 317 x 163 x 107 x 141 x 91 = 709399943070
Therefore, the lowest common multiple of 634,815,535,705,910 is 709399943070.
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.
634 x 815 x 535 x 705 x 910 = 177349985767500
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.
634 : 1, 2, 317, 634
815 : 1, 5, 163, 815
535 : 1, 5, 107, 535
705 : 1, 3, 5, 15, 47, 141, 235, 705
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,815,535,705,910, is 1.
Now, the common factors can be found like this.
634:2x 317
815:5x 163
535:5x 107
705:3x 5x 47
910:2x 5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 177349985767500/(1x250)
LCM = 177349985767500/250
LCM = 709399943070
Thus, we can understand that the LCM of 634,815,535,705,910 is 709399943070.
