Given numbers are 658,545,281,987

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

The LCM of 658,545,281,987 is 302308230.

Find LCM of 658,545,281,987 with Prime Factorization

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

7 x 47 x 2 x 545 x 281 x 3 = 302308230

Therefore, the lowest common multiple of 658,545,281,987 is 302308230.

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.

658 x 545 x 281 x 987 = 99459407670

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

545 : 1, 5, 109, 545

281 : 1, 281

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,545,281,987, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

545:5x 109

281:281

987:3x 7x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 47 = 329

Therefore, the value for common factors is 329.

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 = 99459407670/(1x329)

LCM = 99459407670/329

LCM = 302308230

Thus, we can understand that the LCM of 658,545,281,987 is 302308230.
