Given numbers are 855,773,978,570
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,773,978,570 is 215458290.
Find LCM of 855,773,978,570 with Prime Factorization
2 | 855, 773, 978, 570 |
3 | 855, 773, 489, 285 |
5 | 95, 773, 163, 285 |
19 | 19, 773, 163, 57 |
1, 773, 163, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 773 x 163 x 3 = 215458290
Therefore, the lowest common multiple of 855,773,978,570 is 215458290.
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.
855 x 773 x 978 x 570 = 368433675900
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
773 : 1, 773
978 : 1, 2, 3, 6, 163, 326, 489, 978
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,773,978,570, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
773:773
978:2x 3x 163
570:2x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 19 = 1710
Therefore, the value for common factors is 1710.
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 = 368433675900/(1x1710)
LCM = 368433675900/1710
LCM = 215458290
Thus, we can understand that the LCM of 855,773,978,570 is 215458290.
