Calculate the LCM of 402,972,872,550

Given numbers are 402,972,872,550

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

The LCM of 402,972,872,550 is 3904183800.

Find LCM of 402,972,872,550 with Prime Factorization


2 402, 972, 872, 550
2 201, 486, 436, 275
3 201, 243, 218, 275
67, 81, 218, 275

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

2 x 2 x 3 x 67 x 81 x 218 x 275 = 3904183800

Therefore, the lowest common multiple of 402,972,872,550 is 3904183800.

LCM Formula to Find Lowest Common Multiple of 402,972,872,550

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.

402 x 972 x 872 x 550 = 187400822400

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,972,872,550, is 2.

Now, the common factors can be found like this.

402:2x 3x 67

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

872:2x 2x 2x 109

550:2x 5x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 187400822400/(2x24)

LCM = 187400822400/48

LCM = 3904183800

Thus, we can understand that the LCM of 402,972,872,550 is 3904183800.
