Given numbers are 841,143,689,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 841,143,689,521 is 3320822219.
Find LCM of 841,143,689,521 with Prime Factorization
13 | 841, 143, 689, 521 |
841, 11, 53, 521 |
Multiply the prime numbers at the bottom and the left side.
13 x 841 x 11 x 53 x 521 = 3320822219
Therefore, the lowest common multiple of 841,143,689,521 is 3320822219.
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.
841 x 143 x 689 x 521 = 43170688847
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.
841 : 1, 29, 841
143 : 1, 11, 13, 143
689 : 1, 13, 53, 689
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,143,689,521, is 1.
Now, the common factors can be found like this.
841:29x 29
143:11x 13
689:13x 53
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 43170688847/(1x13)
LCM = 43170688847/13
LCM = 3320822219
Thus, we can understand that the LCM of 841,143,689,521 is 3320822219.
