The LCM of 972,646,769,826 is 99711483732.

Find LCM of 972,646,769,826 with Prime Factorization


2 972, 646, 769, 826
486, 323, 769, 413

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

2 x 486 x 323 x 769 x 413 = 99711483732

Therefore, the lowest common multiple of 972,646,769,826 is 99711483732.

LCM Formula to Find Lowest Common Multiple of 972,646,769,826

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.

972 x 646 x 769 x 826 = 398845934928

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.

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

646 : 1, 2, 17, 19, 34, 38, 323, 646

769 : 1, 769

826 : 1, 2, 7, 14, 59, 118, 413, 826

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,646,769,826, is 1.

Now, the common factors can be found like this.

972:2x 2x 3x 3x 3x 3x 3

646:2x 17x 19

769:769

826:2x 7x 59

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 398845934928/(1x4)

LCM = 398845934928/4

LCM = 99711483732

Thus, we can understand that the LCM of 972,646,769,826 is 99711483732.
