Calculate the LCM of 402,120,387,516

Given numbers are 402,120,387,516

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

The LCM of 402,120,387,516 is 1037160.

Find LCM of 402,120,387,516 with Prime Factorization


2 402, 120, 387, 516
2 201, 60, 387, 258
3 201, 30, 387, 129
43 67, 10, 43, 129
67, 10, 1, 3

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

2 x 2 x 3 x 43 x 67 x 10 x 1 x 3 = 1037160

Therefore, the lowest common multiple of 402,120,387,516 is 1037160.

LCM Formula to Find Lowest Common Multiple of 402,120,387,516

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 120 x 387 x 516 = 9633142080

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

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

387 : 1, 3, 9, 43, 129, 387

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,120,387,516, is 3.

Now, the common factors can be found like this.

402:2x 3x 67

120:2x 2x 2x 3x 5

387:3x 3x 43

516:2x 2x 3x 43

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 3x 3x 43 = 3096

Therefore, the value for common factors is 3096.

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 = 9633142080/(3x3096)

LCM = 9633142080/9288

LCM = 1037160

Thus, we can understand that the LCM of 402,120,387,516 is 1037160.
