The LCM of 732,987,882,561 is 945731556.

Find LCM of 732,987,882,561 with Prime Factorization


2 732, 987, 882, 561
3 366, 987, 441, 561
7 122, 329, 147, 187
122, 47, 21, 187

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

2 x 3 x 7 x 122 x 47 x 21 x 187 = 945731556

Therefore, the lowest common multiple of 732,987,882,561 is 945731556.

LCM Formula to Find Lowest Common Multiple of 732,987,882,561

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.

732 x 987 x 882 x 561 = 357486528168

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.

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

987 : 1, 3, 7, 21, 47, 141, 329, 987

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

561 : 1, 3, 11, 17, 33, 51, 187, 561

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,987,882,561, is 3.

Now, the common factors can be found like this.

732:2x 2x 3x 61

987:3x 7x 47

882:2x 3x 3x 7x 7

561:3x 11x 17

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 7 = 126

Therefore, the value for common factors is 126.

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 = 357486528168/(3x126)

LCM = 357486528168/378

LCM = 945731556

Thus, we can understand that the LCM of 732,987,882,561 is 945731556.
