Given numbers are 860,627,817,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,627,817,771 is 138579540.
Find LCM of 860,627,817,771 with Prime Factorization
3 | 860, 627, 817, 771 |
19 | 860, 209, 817, 257 |
43 | 860, 11, 43, 257 |
20, 11, 1, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 43 x 20 x 11 x 1 x 257 = 138579540
Therefore, the lowest common multiple of 860,627,817,771 is 138579540.
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.
860 x 627 x 817 x 771 = 339658452540
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
627 : 1, 3, 11, 19, 33, 57, 209, 627
817 : 1, 19, 43, 817
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,627,817,771, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
627:3x 11x 19
817:19x 43
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 43 = 2451
Therefore, the value for common factors is 2451.
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 = 339658452540/(1x2451)
LCM = 339658452540/2451
LCM = 138579540
Thus, we can understand that the LCM of 860,627,817,771 is 138579540.
