Given numbers are 640,303,386

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

The LCM of 640,303,386 is 37426560.

Find LCM of 640,303,386 with Prime Factorization

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

2 x 320 x 303 x 193 = 37426560

Therefore, the lowest common multiple of 640,303,386 is 37426560.

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.

640 x 303 x 386 = 74853120

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

303 : 1, 3, 101, 303

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,303,386, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

303:3x 101

386:2x 193

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 = 74853120/(1x2)

LCM = 74853120/2

LCM = 37426560

Thus, we can understand that the LCM of 640,303,386 is 37426560.
