Given numbers are 602,643,728,556,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 602,643,728,556,391 is 1093962324728.
Find LCM of 602,643,728,556,391 with Prime Factorization
| 2 | 602, 643, 728, 556, 391 |
| 2 | 301, 643, 364, 278, 391 |
| 7 | 301, 643, 182, 139, 391 |
| 43, 643, 26, 139, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 43 x 643 x 26 x 139 x 391 = 1093962324728
Therefore, the lowest common multiple of 602,643,728,556,391 is 1093962324728.
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.
602 x 643 x 728 x 556 x 391 = 61261890184768
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.
602 : 1, 2, 7, 14, 43, 86, 301, 602
643 : 1, 643
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
556 : 1, 2, 4, 139, 278, 556
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 602,643,728,556,391, is 1.
Now, the common factors can be found like this.
602:2x 7x 43
643:643
728:2x 2x 2x 7x 13
556:2x 2x 139
391:17x 23
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 2x 7 = 56
Therefore, the value for common factors is 56.
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 = 61261890184768/(1x56)
LCM = 61261890184768/56
LCM = 1093962324728
Thus, we can understand that the LCM of 602,643,728,556,391 is 1093962324728.
