Given numbers are 556,210,290,958
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,210,290,958 is 810956580.
Find LCM of 556,210,290,958 with Prime Factorization
| 2 | 556, 210, 290, 958 |
| 5 | 278, 105, 145, 479 |
| 278, 21, 29, 479 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 278 x 21 x 29 x 479 = 810956580
Therefore, the lowest common multiple of 556,210,290,958 is 810956580.
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.
556 x 210 x 290 x 958 = 32438263200
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.
556 : 1, 2, 4, 139, 278, 556
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
290 : 1, 2, 5, 10, 29, 58, 145, 290
958 : 1, 2, 479, 958
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,210,290,958, is 2.
Now, the common factors can be found like this.
556:2x 2x 139
210:2x 3x 5x 7
290:2x 5x 29
958:2x 479
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 5 = 20
Therefore, the value for common factors is 20.
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 = 32438263200/(2x20)
LCM = 32438263200/40
LCM = 810956580
Thus, we can understand that the LCM of 556,210,290,958 is 810956580.
