Given numbers are 874,437,720,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,437,720,287 is 90301680.
Find LCM of 874,437,720,287 with Prime Factorization
2 | 874, 437, 720, 287 |
19 | 437, 437, 360, 287 |
23 | 23, 23, 360, 287 |
1, 1, 360, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 1 x 1 x 360 x 287 = 90301680
Therefore, the lowest common multiple of 874,437,720,287 is 90301680.
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.
874 x 437 x 720 x 287 = 78923668320
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
437 : 1, 19, 23, 437
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,437,720,287, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
437:19x 23
720:2x 2x 2x 2x 3x 3x 5
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 23 = 874
Therefore, the value for common factors is 874.
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 = 78923668320/(1x874)
LCM = 78923668320/874
LCM = 90301680
Thus, we can understand that the LCM of 874,437,720,287 is 90301680.
