Given numbers are 402,418,185,628

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

The LCM of 402,418,185,628 is 4880605620.

Find LCM of 402,418,185,628 with Prime Factorization

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

2 x 201 x 209 x 185 x 314 = 4880605620

Therefore, the lowest common multiple of 402,418,185,628 is 4880605620.

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 418 x 185 x 628 = 19522422480

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

185 : 1, 5, 37, 185

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,418,185,628, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

418:2x 11x 19

185:5x 37

628:2x 2x 157

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 19522422480/(1x4)

LCM = 19522422480/4

LCM = 4880605620

Thus, we can understand that the LCM of 402,418,185,628 is 4880605620.
