Find the LCM of 620, 321, 107, 691 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 620, 321, 107, 691. So, keep reading to learn more.
Given numbers are 620,321,107,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,321,107,691 is 137522820.
Find LCM of 620,321,107,691 with Prime Factorization
107 | 620, 321, 107, 691 |
620, 3, 1, 691 |
Multiply the prime numbers at the bottom and the left side.
107 x 620 x 3 x 1 x 691 = 137522820
Therefore, the lowest common multiple of 620,321,107,691 is 137522820.
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.
620 x 321 x 107 x 691 = 14714941740
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
321 : 1, 3, 107, 321
107 : 1, 107
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,321,107,691, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
321:3x 107
107:107
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
107 = 107
Therefore, the value for common factors is 107.
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 = 14714941740/(1x107)
LCM = 14714941740/107
LCM = 137522820
Thus, we can understand that the LCM of 620,321,107,691 is 137522820.
