Given numbers are 639,228,201,642,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,228,201,642,722 is 6614951004.
Find LCM of 639,228,201,642,722 with Prime Factorization
| 2 | 639, 228, 201, 642, 722 |
| 3 | 639, 114, 201, 321, 361 |
| 19 | 213, 38, 67, 107, 361 |
| 213, 2, 67, 107, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 213 x 2 x 67 x 107 x 19 = 6614951004
Therefore, the lowest common multiple of 639,228,201,642,722 is 6614951004.
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 228 x 201 x 642 x 722 = 13573879460208
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
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
201 : 1, 3, 67, 201
642 : 1, 2, 3, 6, 107, 214, 321, 642
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,228,201,642,722, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
228:2x 2x 3x 19
201:3x 67
642:2x 3x 107
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 19 = 2052
Therefore, the value for common factors is 2052.
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 = 13573879460208/(1x2052)
LCM = 13573879460208/2052
LCM = 6614951004
Thus, we can understand that the LCM of 639,228,201,642,722 is 6614951004.
