Given numbers are 902,112,802,987,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,112,802,987,663 is 631175777232.
Find LCM of 902,112,802,987,663 with Prime Factorization
| 2 | 902, 112, 802, 987, 663 |
| 3 | 451, 56, 401, 987, 663 |
| 7 | 451, 56, 401, 329, 221 |
| 451, 8, 401, 47, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 451 x 8 x 401 x 47 x 221 = 631175777232
Therefore, the lowest common multiple of 902,112,802,987,663 is 631175777232.
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 112 x 802 x 987 x 663 = 53018765287488
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
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
802 : 1, 2, 401, 802
987 : 1, 3, 7, 21, 47, 141, 329, 987
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,112,802,987,663, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
112:2x 2x 2x 2x 7
802:2x 401
987:3x 7x 47
663:3x 13x 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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 53018765287488/(1x84)
LCM = 53018765287488/84
LCM = 631175777232
Thus, we can understand that the LCM of 902,112,802,987,663 is 631175777232.
