Given numbers are 197,880,642

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

The LCM of 197,880,642 is 55648560.

Find LCM of 197,880,642 with Prime Factorization

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

2 x 197 x 440 x 321 = 55648560

Therefore, the lowest common multiple of 197,880,642 is 55648560.

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.

197 x 880 x 642 = 111297120

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.

197 : 1, 197

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,880,642, is 1.

Now, the common factors can be found like this.

197:197

880:2x 2x 2x 2x 5x 11

642:2x 3x 107

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 = 111297120/(1x2)

LCM = 111297120/2

LCM = 55648560

Thus, we can understand that the LCM of 197,880,642 is 55648560.

Here are some samples of LCM of two or more Numbers calculations.
