Given numbers are 643,146,114,185

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

The LCM of 643,146,114,185 is 989943510.

Find LCM of 643,146,114,185 with Prime Factorization

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

2 x 643 x 73 x 57 x 185 = 989943510

Therefore, the lowest common multiple of 643,146,114,185 is 989943510.

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.

643 x 146 x 114 x 185 = 1979887020

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.

643 : 1, 643

146 : 1, 2, 73, 146

114 : 1, 2, 3, 6, 19, 38, 57, 114

185 : 1, 5, 37, 185

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,146,114,185, is 1.

Now, the common factors can be found like this.

643:643

146:2x 73

114:2x 3x 19

185:5x 37

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 = 1979887020/(1x2)

LCM = 1979887020/2

LCM = 989943510

Thus, we can understand that the LCM of 643,146,114,185 is 989943510.
