Given numbers are 941,640,798,815,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 941,640,798,815,681 is 8891109413760.
Find LCM of 941,640,798,815,681 with Prime Factorization
| 2 | 941, 640, 798, 815, 681 |
| 3 | 941, 320, 399, 815, 681 |
| 5 | 941, 320, 133, 815, 227 |
| 941, 64, 133, 163, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 941 x 64 x 133 x 163 x 227 = 8891109413760
Therefore, the lowest common multiple of 941,640,798,815,681 is 8891109413760.
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.
941 x 640 x 798 x 815 x 681 = 266733282412800
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.
941 : 1, 941
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
815 : 1, 5, 163, 815
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 941,640,798,815,681, is 1.
Now, the common factors can be found like this.
941:941
640:2x 2x 2x 2x 2x 2x 2x 5
798:2x 3x 7x 19
815:5x 163
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 266733282412800/(1x30)
LCM = 266733282412800/30
LCM = 8891109413760
Thus, we can understand that the LCM of 941,640,798,815,681 is 8891109413760.
