Given numbers are 491,138,473,146

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

The LCM of 491,138,473,146 is 2339615982.

Find LCM of 491,138,473,146 with Prime Factorization

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

2 x 491 x 69 x 473 x 73 = 2339615982

Therefore, the lowest common multiple of 491,138,473,146 is 2339615982.

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.

491 x 138 x 473 x 146 = 4679231964

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.

491 : 1, 491

138 : 1, 2, 3, 6, 23, 46, 69, 138

473 : 1, 11, 43, 473

146 : 1, 2, 73, 146

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,138,473,146, is 1.

Now, the common factors can be found like this.

491:491

138:2x 3x 23

473:11x 43

146:2x 73

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 = 4679231964/(1x2)

LCM = 4679231964/2

LCM = 2339615982

Thus, we can understand that the LCM of 491,138,473,146 is 2339615982.
