Given numbers are 436,870,989,258
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,870,989,258 is 187573740.
Find LCM of 436,870,989,258 with Prime Factorization
2 | 436, 870, 989, 258 |
3 | 218, 435, 989, 129 |
43 | 218, 145, 989, 43 |
218, 145, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 218 x 145 x 23 x 1 = 187573740
Therefore, the lowest common multiple of 436,870,989,258 is 187573740.
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.
436 x 870 x 989 x 258 = 96788049840
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.
436 : 1, 2, 4, 109, 218, 436
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
989 : 1, 23, 43, 989
258 : 1, 2, 3, 6, 43, 86, 129, 258
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,870,989,258, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
870:2x 3x 5x 29
989:23x 43
258:2x 3x 43
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 3x 43 = 516
Therefore, the value for common factors is 516.
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 = 96788049840/(1x516)
LCM = 96788049840/516
LCM = 187573740
Thus, we can understand that the LCM of 436,870,989,258 is 187573740.
