Given numbers are 902,217,805,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,217,805,820 is 45018820.
Find LCM of 902,217,805,820 with Prime Factorization
2 | 902, 217, 805, 820 |
5 | 451, 217, 805, 410 |
7 | 451, 217, 161, 82 |
41 | 451, 31, 23, 82 |
11, 31, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 41 x 11 x 31 x 23 x 2 = 45018820
Therefore, the lowest common multiple of 902,217,805,820 is 45018820.
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.
902 x 217 x 805 x 820 = 129204013400
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
217 : 1, 7, 31, 217
805 : 1, 5, 7, 23, 35, 115, 161, 805
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,217,805,820, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
217:7x 31
805:5x 7x 23
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 41 = 2870
Therefore, the value for common factors is 2870.
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 = 129204013400/(1x2870)
LCM = 129204013400/2870
LCM = 45018820
Thus, we can understand that the LCM of 902,217,805,820 is 45018820.
