Given numbers are 855,119,578,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,119,578,425 is 17296650.
Find LCM of 855,119,578,425 with Prime Factorization
| 5 | 855, 119, 578, 425 |
| 17 | 171, 119, 578, 85 |
| 171, 7, 34, 5 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 171 x 7 x 34 x 5 = 17296650
Therefore, the lowest common multiple of 855,119,578,425 is 17296650.
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 119 x 578 x 425 = 24993659250
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
119 : 1, 7, 17, 119
578 : 1, 2, 17, 34, 289, 578
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,119,578,425, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
119:7x 17
578:2x 17x 17
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17x 17 = 1445
Therefore, the value for common factors is 1445.
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 = 24993659250/(1x1445)
LCM = 24993659250/1445
LCM = 17296650
Thus, we can understand that the LCM of 855,119,578,425 is 17296650.
