Given numbers are 798,442,850,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 798,442,850,680 is 17635800.
Find LCM of 798,442,850,680 with Prime Factorization
2 | 798, 442, 850, 680 |
5 | 399, 221, 425, 340 |
17 | 399, 221, 85, 68 |
399, 13, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 399 x 13 x 5 x 4 = 17635800
Therefore, the lowest common multiple of 798,442,850,680 is 17635800.
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.
798 x 442 x 850 x 680 = 203869848000
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
442 : 1, 2, 13, 17, 26, 34, 221, 442
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,442,850,680, is 2.
Now, the common factors can be found like this.
798:2x 3x 7x 19
442:2x 13x 17
850:2x 5x 5x 17
680:2x 2x 2x 5x 17
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 5x 17x 17 = 5780
Therefore, the value for common factors is 5780.
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 = 203869848000/(2x5780)
LCM = 203869848000/11560
LCM = 17635800
Thus, we can understand that the LCM of 798,442,850,680 is 17635800.
