Calculate the LCM of 972,288,412,661

Given numbers are 972,288,412,661

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 972,288,412,661 is 529413408.

Find LCM of 972,288,412,661 with Prime Factorization


2 972, 288, 412, 661
2 486, 144, 206, 661
3 243, 72, 103, 661
3 81, 24, 103, 661
27, 8, 103, 661

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

2 x 2 x 3 x 3 x 27 x 8 x 103 x 661 = 529413408

Therefore, the lowest common multiple of 972,288,412,661 is 529413408.

LCM Formula to Find Lowest Common Multiple of 972,288,412,661

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 288 x 412 x 661 = 76235530752

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

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

412 : 1, 2, 4, 103, 206, 412

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,288,412,661, is 1.

Now, the common factors can be found like this.

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

288:2x 2x 2x 2x 2x 3x 3

412:2x 2x 103

661:661

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

2x 2x 2x 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 76235530752/(1x144)

LCM = 76235530752/144

LCM = 529413408

Thus, we can understand that the LCM of 972,288,412,661 is 529413408.
