Given numbers are 961,778,978,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,778,978,858 is 52281480966.
Find LCM of 961,778,978,858 with Prime Factorization
2 | 961, 778, 978, 858 |
3 | 961, 389, 489, 429 |
961, 389, 163, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 961 x 389 x 163 x 143 = 52281480966
Therefore, the lowest common multiple of 961,778,978,858 is 52281480966.
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.
961 x 778 x 978 x 858 = 627377771592
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.
961 : 1, 31, 961
778 : 1, 2, 389, 778
978 : 1, 2, 3, 6, 163, 326, 489, 978
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,778,978,858, is 1.
Now, the common factors can be found like this.
961:31x 31
778:2x 389
978:2x 3x 163
858:2x 3x 11x 13
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 3 = 12
Therefore, the value for common factors is 12.
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 = 627377771592/(1x12)
LCM = 627377771592/12
LCM = 52281480966
Thus, we can understand that the LCM of 961,778,978,858 is 52281480966.
