Given numbers are 859,215,614,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,215,614,420 is 4762656780.
Find LCM of 859,215,614,420 with Prime Factorization
2 | 859, 215, 614, 420 |
5 | 859, 215, 307, 210 |
859, 43, 307, 42 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 859 x 43 x 307 x 42 = 4762656780
Therefore, the lowest common multiple of 859,215,614,420 is 4762656780.
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.
859 x 215 x 614 x 420 = 47626567800
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.
859 : 1, 859
215 : 1, 5, 43, 215
614 : 1, 2, 307, 614
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,215,614,420, is 1.
Now, the common factors can be found like this.
859:859
215:5x 43
614:2x 307
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 47626567800/(1x10)
LCM = 47626567800/10
LCM = 4762656780
Thus, we can understand that the LCM of 859,215,614,420 is 4762656780.
