Given numbers are 919,742,338,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 919,742,338,721 is 11869798486.
Find LCM of 919,742,338,721 with Prime Factorization
2 | 919, 742, 338, 721 |
7 | 919, 371, 169, 721 |
919, 53, 169, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 919 x 53 x 169 x 103 = 11869798486
Therefore, the lowest common multiple of 919,742,338,721 is 11869798486.
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.
919 x 742 x 338 x 721 = 166177178804
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.
919 : 1, 919
742 : 1, 2, 7, 14, 53, 106, 371, 742
338 : 1, 2, 13, 26, 169, 338
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,742,338,721, is 1.
Now, the common factors can be found like this.
919:919
742:2x 7x 53
338:2x 13x 13
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 166177178804/(1x14)
LCM = 166177178804/14
LCM = 11869798486
Thus, we can understand that the LCM of 919,742,338,721 is 11869798486.
