The LCM of 946,909,969,861 is 79714887714.

Find LCM of 946,909,969,861 with Prime Factorization


3 946, 909, 969, 861
946, 303, 323, 287

Multiply the prime numbers at the bottom and the left side.

3 x 946 x 303 x 323 x 287 = 79714887714

Therefore, the lowest common multiple of 946,909,969,861 is 79714887714.

LCM Formula to Find Lowest Common Multiple of 946,909,969,861

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.

946 x 909 x 969 x 861 = 717433989426

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

909 : 1, 3, 9, 101, 303, 909

969 : 1, 3, 17, 19, 51, 57, 323, 969

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,909,969,861, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

909:3x 3x 101

969:3x 17x 19

861:3x 7x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 717433989426/(1x9)

LCM = 717433989426/9

LCM = 79714887714

Thus, we can understand that the LCM of 946,909,969,861 is 79714887714.
