Find the LCM of 770, 691, 691, 661 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 770, 691, 691, 661. So, keep reading to learn more.
Given numbers are 770,691,691,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,691,691,661 is 351698270.
Find LCM of 770,691,691,661 with Prime Factorization
691 | 770, 691, 691, 661 |
770, 1, 1, 661 |
Multiply the prime numbers at the bottom and the left side.
691 x 770 x 1 x 1 x 661 = 351698270
Therefore, the lowest common multiple of 770,691,691,661 is 351698270.
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.
770 x 691 x 691 x 661 = 243023504570
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
691 : 1, 691
691 : 1, 691
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,691,691,661, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
691:691
691:691
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
691 = 691
Therefore, the value for common factors is 691.
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 = 243023504570/(1x691)
LCM = 243023504570/691
LCM = 351698270
Thus, we can understand that the LCM of 770,691,691,661 is 351698270.
