Given numbers are 639,310,899,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,310,899,901 is 5175893610.
Find LCM of 639,310,899,901 with Prime Factorization
31 | 639, 310, 899, 901 |
639, 10, 29, 901 |
Multiply the prime numbers at the bottom and the left side.
31 x 639 x 10 x 29 x 901 = 5175893610
Therefore, the lowest common multiple of 639,310,899,901 is 5175893610.
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.
639 x 310 x 899 x 901 = 160452701910
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.
639 : 1, 3, 9, 71, 213, 639
310 : 1, 2, 5, 10, 31, 62, 155, 310
899 : 1, 29, 31, 899
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,310,899,901, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
310:2x 5x 31
899:29x 31
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31 = 31
Therefore, the value for common factors is 31.
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 = 160452701910/(1x31)
LCM = 160452701910/31
LCM = 5175893610
Thus, we can understand that the LCM of 639,310,899,901 is 5175893610.
