Given numbers are 620,814,402

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

The LCM of 620,814,402 is 50720340.

Find LCM of 620,814,402 with Prime Factorization

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

2 x 310 x 407 x 201 = 50720340

Therefore, the lowest common multiple of 620,814,402 is 50720340.

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.

620 x 814 x 402 = 202881360

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

814 : 1, 2, 11, 22, 37, 74, 407, 814

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,814,402, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

814:2x 11x 37

402:2x 3x 67

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

2 = 2

Therefore, the value for common factors is 2.

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 = 202881360/(2x2)

LCM = 202881360/4

LCM = 50720340

Thus, we can understand that the LCM of 620,814,402 is 50720340.
