Given numbers are 639,451,407,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,451,407,546 is 1940664726.
Find LCM of 639,451,407,546 with Prime Factorization
3 | 639, 451, 407, 546 |
11 | 213, 451, 407, 182 |
213, 41, 37, 182 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 213 x 41 x 37 x 182 = 1940664726
Therefore, the lowest common multiple of 639,451,407,546 is 1940664726.
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 451 x 407 x 546 = 64041935958
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
451 : 1, 11, 41, 451
407 : 1, 11, 37, 407
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,451,407,546, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
451:11x 41
407:11x 37
546:2x 3x 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.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 64041935958/(1x33)
LCM = 64041935958/33
LCM = 1940664726
Thus, we can understand that the LCM of 639,451,407,546 is 1940664726.
