Given numbers are 866,417,842,253,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,417,842,253,278 is 38464187586.
Find LCM of 866,417,842,253,278 with Prime Factorization
| 2 | 866, 417, 842, 253, 278 |
| 139 | 433, 417, 421, 253, 139 |
| 433, 3, 421, 253, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 433 x 3 x 421 x 253 x 1 = 38464187586
Therefore, the lowest common multiple of 866,417,842,253,278 is 38464187586.
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.
866 x 417 x 842 x 253 x 278 = 21386088297816
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.
866 : 1, 2, 433, 866
417 : 1, 3, 139, 417
842 : 1, 2, 421, 842
253 : 1, 11, 23, 253
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,417,842,253,278, is 1.
Now, the common factors can be found like this.
866:2x 433
417:3x 139
842:2x 421
253:11x 23
278:2x 139
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 139 = 556
Therefore, the value for common factors is 556.
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 = 21386088297816/(1x556)
LCM = 21386088297816/556
LCM = 38464187586
Thus, we can understand that the LCM of 866,417,842,253,278 is 38464187586.
