Given numbers are 874,805,763,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,805,763,774 is 1290377970.
Find LCM of 874,805,763,774 with Prime Factorization
2 | 874, 805, 763, 774 |
7 | 437, 805, 763, 387 |
23 | 437, 115, 109, 387 |
19, 5, 109, 387 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 19 x 5 x 109 x 387 = 1290377970
Therefore, the lowest common multiple of 874,805,763,774 is 1290377970.
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.
874 x 805 x 763 x 774 = 415501706340
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
805 : 1, 5, 7, 23, 35, 115, 161, 805
763 : 1, 7, 109, 763
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,805,763,774, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
805:5x 7x 23
763:7x 109
774:2x 3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 23 = 322
Therefore, the value for common factors is 322.
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 = 415501706340/(1x322)
LCM = 415501706340/322
LCM = 1290377970
Thus, we can understand that the LCM of 874,805,763,774 is 1290377970.
