Given numbers are 639,832,979,221,571
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,832,979,221,571 is 5052332286144.
Find LCM of 639,832,979,221,571 with Prime Factorization
13 | 639, 832, 979, 221, 571 |
639, 64, 979, 17, 571 |
Multiply the prime numbers at the bottom and the left side.
13 x 639 x 64 x 979 x 17 x 571 = 5052332286144
Therefore, the lowest common multiple of 639,832,979,221,571 is 5052332286144.
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 832 x 979 x 221 x 571 = 65680319719872
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
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
979 : 1, 11, 89, 979
221 : 1, 13, 17, 221
571 : 1, 571
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,832,979,221,571, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
832:2x 2x 2x 2x 2x 2x 13
979:11x 89
221:13x 17
571:571
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 65680319719872/(1x13)
LCM = 65680319719872/13
LCM = 5052332286144
Thus, we can understand that the LCM of 639,832,979,221,571 is 5052332286144.
