Given numbers are 94,32,63,642

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

The LCM of 94,32,63,642 is 10138464.

Find LCM of 94,32,63,642 with Prime Factorization

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

2 x 3 x 47 x 16 x 21 x 107 = 10138464

Therefore, the lowest common multiple of 94,32,63,642 is 10138464.

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.

94 x 32 x 63 x 642 = 121661568

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.

94 : 1, 2, 47, 94

32 : 1, 2, 4, 8, 16, 32

63 : 1, 3, 7, 9, 21, 63

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 94,32,63,642, is 1.

Now, the common factors can be found like this.

94:2x 47

32:2x 2x 2x 2x 2

63:3x 3x 7

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.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 121661568/(1x12)

LCM = 121661568/12

LCM = 10138464

Thus, we can understand that the LCM of 94,32,63,642 is 10138464.
