Given numbers are 562,426,762,168,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 562,426,762,168,646 is 137492875128.
Find LCM of 562,426,762,168,646 with Prime Factorization
| 2 | 562, 426, 762, 168, 646 |
| 3 | 281, 213, 381, 84, 323 |
| 281, 71, 127, 28, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 281 x 71 x 127 x 28 x 323 = 137492875128
Therefore, the lowest common multiple of 562,426,762,168,646 is 137492875128.
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.
562 x 426 x 762 x 168 x 646 = 19798974018432
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.
562 : 1, 2, 281, 562
426 : 1, 2, 3, 6, 71, 142, 213, 426
762 : 1, 2, 3, 6, 127, 254, 381, 762
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
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 562,426,762,168,646, is 2.
Now, the common factors can be found like this.
562:2x 281
426:2x 3x 71
762:2x 3x 127
168:2x 2x 2x 3x 7
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 19798974018432/(2x72)
LCM = 19798974018432/144
LCM = 137492875128
Thus, we can understand that the LCM of 562,426,762,168,646 is 137492875128.
