The LCM of 777,864,963,990 is 1316921760.

Find LCM of 777,864,963,990 with Prime Factorization


2 777, 864, 963, 990
3 777, 432, 963, 495
3 259, 144, 321, 165
259, 48, 107, 55

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

2 x 3 x 3 x 259 x 48 x 107 x 55 = 1316921760

Therefore, the lowest common multiple of 777,864,963,990 is 1316921760.

LCM Formula to Find Lowest Common Multiple of 777,864,963,990

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.

777 x 864 x 963 x 990 = 640023975360

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

963 : 1, 3, 9, 107, 321, 963

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,864,963,990, is 3.

Now, the common factors can be found like this.

777:3x 7x 37

864:2x 2x 2x 2x 2x 3x 3x 3

963:3x 3x 107

990:2x 3x 3x 5x 11

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 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 640023975360/(3x162)

LCM = 640023975360/486

LCM = 1316921760

Thus, we can understand that the LCM of 777,864,963,990 is 1316921760.
