Given numbers are 207,865,920,578,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,865,920,578,242 is 50090994360.
Find LCM of 207,865,920,578,242 with Prime Factorization
| 2 | 207, 865, 920, 578, 242 |
| 5 | 207, 865, 460, 289, 121 |
| 23 | 207, 173, 92, 289, 121 |
| 9, 173, 4, 289, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 9 x 173 x 4 x 289 x 121 = 50090994360
Therefore, the lowest common multiple of 207,865,920,578,242 is 50090994360.
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.
207 x 865 x 920 x 578 x 242 = 23041857405600
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.
207 : 1, 3, 9, 23, 69, 207
865 : 1, 5, 173, 865
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
578 : 1, 2, 17, 34, 289, 578
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,865,920,578,242, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
865:5x 173
920:2x 2x 2x 5x 23
578:2x 17x 17
242:2x 11x 11
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 23041857405600/(1x460)
LCM = 23041857405600/460
LCM = 50090994360
Thus, we can understand that the LCM of 207,865,920,578,242 is 50090994360.
