Given numbers are 427,398,385,287,987

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

The LCM of 427,398,385,287,987 is 54035180430.

Find LCM of 427,398,385,287,987 with Prime Factorization

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

7 x 61 x 398 x 55 x 41 x 141 = 54035180430

Therefore, the lowest common multiple of 427,398,385,287,987 is 54035180430.

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.

427 x 398 x 385 x 287 x 987 = 18534066887490

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.

427 : 1, 7, 61, 427

398 : 1, 2, 199, 398

385 : 1, 5, 7, 11, 35, 55, 77, 385

287 : 1, 7, 41, 287

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 427,398,385,287,987, is 1.

Now, the common factors can be found like this.

427:7x 61

398:2x 199

385:5x 7x 11

287:7x 41

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 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 18534066887490/(1x343)

LCM = 18534066887490/343

LCM = 54035180430

Thus, we can understand that the LCM of 427,398,385,287,987 is 54035180430.
