Given numbers are 799,216,420,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,216,420,894 is 900025560.
Find LCM of 799,216,420,894 with Prime Factorization
| 2 | 799, 216, 420, 894 |
| 2 | 799, 108, 210, 447 |
| 3 | 799, 54, 105, 447 |
| 799, 18, 35, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 799 x 18 x 35 x 149 = 900025560
Therefore, the lowest common multiple of 799,216,420,894 is 900025560.
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.
799 x 216 x 420 x 894 = 64801840320
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.
799 : 1, 17, 47, 799
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
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
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,216,420,894, is 1.
Now, the common factors can be found like this.
799:17x 47
216:2x 2x 2x 3x 3x 3
420:2x 2x 3x 5x 7
894:2x 3x 149
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 64801840320/(1x72)
LCM = 64801840320/72
LCM = 900025560
Thus, we can understand that the LCM of 799,216,420,894 is 900025560.
