Given numbers are 221,759,802,668,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,759,802,668,905 is 40663378959060.
Find LCM of 221,759,802,668,905 with Prime Factorization
2 | 221, 759, 802, 668, 905 |
221, 759, 401, 334, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 221 x 759 x 401 x 334 x 905 = 40663378959060
Therefore, the lowest common multiple of 221,759,802,668,905 is 40663378959060.
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.
221 x 759 x 802 x 668 x 905 = 81326757918120
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.
221 : 1, 13, 17, 221
759 : 1, 3, 11, 23, 33, 69, 253, 759
802 : 1, 2, 401, 802
668 : 1, 2, 4, 167, 334, 668
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,759,802,668,905, is 1.
Now, the common factors can be found like this.
221:13x 17
759:3x 11x 23
802:2x 401
668:2x 2x 167
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 81326757918120/(1x2)
LCM = 81326757918120/2
LCM = 40663378959060
Thus, we can understand that the LCM of 221,759,802,668,905 is 40663378959060.
