Given numbers are 418,800,602,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,800,602,646 is 855562400.
Find LCM of 418,800,602,646 with Prime Factorization
2 | 418, 800, 602, 646 |
19 | 209, 400, 301, 323 |
11, 400, 301, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 11 x 400 x 301 x 17 = 855562400
Therefore, the lowest common multiple of 418,800,602,646 is 855562400.
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.
418 x 800 x 602 x 646 = 130045484800
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
602 : 1, 2, 7, 14, 43, 86, 301, 602
646 : 1, 2, 17, 19, 34, 38, 323, 646
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,800,602,646, is 2.
Now, the common factors can be found like this.
418:2x 11x 19
800:2x 2x 2x 2x 2x 5x 5
602:2x 7x 43
646:2x 17x 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 19 = 76
Therefore, the value for common factors is 76.
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 = 130045484800/(2x76)
LCM = 130045484800/152
LCM = 855562400
Thus, we can understand that the LCM of 418,800,602,646 is 855562400.
