Given numbers are 802,401,783,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,401,783,121 is 75983886.
Find LCM of 802,401,783,121 with Prime Factorization
401 | 802, 401, 783, 121 |
2, 1, 783, 121 |
Multiply the prime numbers at the bottom and the left side.
401 x 2 x 1 x 783 x 121 = 75983886
Therefore, the lowest common multiple of 802,401,783,121 is 75983886.
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.
802 x 401 x 783 x 121 = 30469538286
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.
802 : 1, 2, 401, 802
401 : 1, 401
783 : 1, 3, 9, 27, 29, 87, 261, 783
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,401,783,121, is 1.
Now, the common factors can be found like this.
802:2x 401
401:401
783:3x 3x 3x 29
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
401 = 401
Therefore, the value for common factors is 401.
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 = 30469538286/(1x401)
LCM = 30469538286/401
LCM = 75983886
Thus, we can understand that the LCM of 802,401,783,121 is 75983886.
