Given numbers are 639,301,856,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,301,856,494 is 40666619448.
Find LCM of 639,301,856,494 with Prime Factorization
2 | 639, 301, 856, 494 |
639, 301, 428, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 639 x 301 x 428 x 247 = 40666619448
Therefore, the lowest common multiple of 639,301,856,494 is 40666619448.
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 301 x 856 x 494 = 81333238896
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
301 : 1, 7, 43, 301
856 : 1, 2, 4, 8, 107, 214, 428, 856
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,301,856,494, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
301:7x 43
856:2x 2x 2x 107
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 81333238896/(1x2)
LCM = 81333238896/2
LCM = 40666619448
Thus, we can understand that the LCM of 639,301,856,494 is 40666619448.
