Given numbers are 442,991,730,387

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

The LCM of 442,991,730,387 is 61872797610.

Find LCM of 442,991,730,387 with Prime Factorization

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

2 x 221 x 991 x 365 x 387 = 61872797610

Therefore, the lowest common multiple of 442,991,730,387 is 61872797610.

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.

442 x 991 x 730 x 387 = 123745595220

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

991 : 1, 991

730 : 1, 2, 5, 10, 73, 146, 365, 730

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,991,730,387, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

991:991

730:2x 5x 73

387:3x 3x 43

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 = 123745595220/(1x2)

LCM = 123745595220/2

LCM = 61872797610

Thus, we can understand that the LCM of 442,991,730,387 is 61872797610.
