Given numbers are 803,680,889,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,680,889,221 is 6310584280.
Find LCM of 803,680,889,221 with Prime Factorization
| 17 | 803, 680, 889, 221 |
| 803, 40, 889, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 803 x 40 x 889 x 13 = 6310584280
Therefore, the lowest common multiple of 803,680,889,221 is 6310584280.
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.
803 x 680 x 889 x 221 = 107279932760
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.
803 : 1, 11, 73, 803
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
889 : 1, 7, 127, 889
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,680,889,221, is 1.
Now, the common factors can be found like this.
803:11x 73
680:2x 2x 2x 5x 17
889:7x 127
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 107279932760/(1x17)
LCM = 107279932760/17
LCM = 6310584280
Thus, we can understand that the LCM of 803,680,889,221 is 6310584280.
