Given numbers are 514,987,646,257

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

The LCM of 514,987,646,257 is 163863714.

Find LCM of 514,987,646,257 with Prime Factorization

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

2 x 257 x 1 x 987 x 323 x 1 = 163863714

Therefore, the lowest common multiple of 514,987,646,257 is 163863714.

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.

514 x 987 x 646 x 257 = 84225948996

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.

514 : 1, 2, 257, 514

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 514,987,646,257, is 1.

Now, the common factors can be found like this.

514:2x 257

987:3x 7x 47

646:2x 17x 19

257:257

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

2x 257 = 514

Therefore, the value for common factors is 514.

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 = 84225948996/(1x514)

LCM = 84225948996/514

LCM = 163863714

Thus, we can understand that the LCM of 514,987,646,257 is 163863714.
