Find the LCM of 851, 842, 851, 545 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 851, 842, 851, 545. So, keep reading to learn more.
Given numbers are 851,842,851,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,842,851,545 is 390515390.
Find LCM of 851,842,851,545 with Prime Factorization
23 | 851, 842, 851, 545 |
37 | 37, 842, 37, 545 |
1, 842, 1, 545 |
Multiply the prime numbers at the bottom and the left side.
23 x 37 x 1 x 842 x 1 x 545 = 390515390
Therefore, the lowest common multiple of 851,842,851,545 is 390515390.
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.
851 x 842 x 851 x 545 = 332328596890
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.
851 : 1, 23, 37, 851
842 : 1, 2, 421, 842
851 : 1, 23, 37, 851
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,842,851,545, is 1.
Now, the common factors can be found like this.
851:23x 37
842:2x 421
851:23x 37
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 37 = 851
Therefore, the value for common factors is 851.
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 = 332328596890/(1x851)
LCM = 332328596890/851
LCM = 390515390
Thus, we can understand that the LCM of 851,842,851,545 is 390515390.
