Given numbers are 715,685,384,556,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,685,384,556,653 is 3414175290240.
Find LCM of 715,685,384,556,653 with Prime Factorization
| 2 | 715, 685, 384, 556, 653 |
| 2 | 715, 685, 192, 278, 653 |
| 5 | 715, 685, 96, 139, 653 |
| 143, 137, 96, 139, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 143 x 137 x 96 x 139 x 653 = 3414175290240
Therefore, the lowest common multiple of 715,685,384,556,653 is 3414175290240.
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.
715 x 685 x 384 x 556 x 653 = 68283505804800
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
685 : 1, 5, 137, 685
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
556 : 1, 2, 4, 139, 278, 556
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,685,384,556,653, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
685:5x 137
384:2x 2x 2x 2x 2x 2x 2x 3
556:2x 2x 139
653:653
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 5 = 20
Therefore, the value for common factors is 20.
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 = 68283505804800/(1x20)
LCM = 68283505804800/20
LCM = 3414175290240
Thus, we can understand that the LCM of 715,685,384,556,653 is 3414175290240.
