Given numbers are 666,781,278,313,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 666,781,278,313,745 is 16859344056390.
Find LCM of 666,781,278,313,745 with Prime Factorization
| 2 | 666, 781, 278, 313, 745 |
| 333, 781, 139, 313, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 333 x 781 x 139 x 313 x 745 = 16859344056390
Therefore, the lowest common multiple of 666,781,278,313,745 is 16859344056390.
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.
666 x 781 x 278 x 313 x 745 = 33718688112780
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.
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
781 : 1, 11, 71, 781
278 : 1, 2, 139, 278
313 : 1, 313
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,781,278,313,745, is 1.
Now, the common factors can be found like this.
666:2x 3x 3x 37
781:11x 71
278:2x 139
313:313
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 33718688112780/(1x2)
LCM = 33718688112780/2
LCM = 16859344056390
Thus, we can understand that the LCM of 666,781,278,313,745 is 16859344056390.
