Given numbers are 290,689,869,87
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,689,869,87 is 520904670.
Find LCM of 290,689,869,87 with Prime Factorization
29 | 290, 689, 869, 87 |
10, 689, 869, 3 |
Multiply the prime numbers at the bottom and the left side.
29 x 10 x 689 x 869 x 3 = 520904670
Therefore, the lowest common multiple of 290,689,869,87 is 520904670.
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.
290 x 689 x 869 x 87 = 15106235430
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
689 : 1, 13, 53, 689
869 : 1, 11, 79, 869
87 : 1, 3, 29, 87
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,689,869,87, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
689:13x 53
869:11x 79
87:3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29 = 29
Therefore, the value for common factors is 29.
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 = 15106235430/(1x29)
LCM = 15106235430/29
LCM = 520904670
Thus, we can understand that the LCM of 290,689,869,87 is 520904670.
