Given numbers are 821,121,143,389,601
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,121,143,389,601 is 301922829637.
Find LCM of 821,121,143,389,601 with Prime Factorization
11 | 821, 121, 143, 389, 601 |
821, 11, 13, 389, 601 |
Multiply the prime numbers at the bottom and the left side.
11 x 821 x 11 x 13 x 389 x 601 = 301922829637
Therefore, the lowest common multiple of 821,121,143,389,601 is 301922829637.
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.
821 x 121 x 143 x 389 x 601 = 3321151126007
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.
821 : 1, 821
121 : 1, 11, 121
143 : 1, 11, 13, 143
389 : 1, 389
601 : 1, 601
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,121,143,389,601, is 1.
Now, the common factors can be found like this.
821:821
121:11x 11
143:11x 13
389:389
601:601
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 3321151126007/(1x11)
LCM = 3321151126007/11
LCM = 301922829637
Thus, we can understand that the LCM of 821,121,143,389,601 is 301922829637.
