Given numbers are 680,161,598,487

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

The LCM of 680,161,598,487 is 693117880.

Find LCM of 680,161,598,487 with Prime Factorization

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

2 x 23 x 340 x 7 x 13 x 487 = 693117880

Therefore, the lowest common multiple of 680,161,598,487 is 693117880.

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.

680 x 161 x 598 x 487 = 31883422480

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

161 : 1, 7, 23, 161

598 : 1, 2, 13, 23, 26, 46, 299, 598

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,161,598,487, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

161:7x 23

598:2x 13x 23

487:487

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 31883422480/(1x46)

LCM = 31883422480/46

LCM = 693117880

Thus, we can understand that the LCM of 680,161,598,487 is 693117880.
