Given numbers are 139,618,690,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,618,690,943 is 405027930.
Find LCM of 139,618,690,943 with Prime Factorization
2 | 139, 618, 690, 943 |
3 | 139, 309, 345, 943 |
23 | 139, 103, 115, 943 |
139, 103, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 139 x 103 x 5 x 41 = 405027930
Therefore, the lowest common multiple of 139,618,690,943 is 405027930.
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.
139 x 618 x 690 x 943 = 55893854340
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.
139 : 1, 139
618 : 1, 2, 3, 6, 103, 206, 309, 618
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,618,690,943, is 1.
Now, the common factors can be found like this.
139:139
618:2x 3x 103
690:2x 3x 5x 23
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 55893854340/(1x138)
LCM = 55893854340/138
LCM = 405027930
Thus, we can understand that the LCM of 139,618,690,943 is 405027930.
