Given numbers are 769,818,521,680

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

The LCM of 769,818,521,680 is 111428499880.

Find LCM of 769,818,521,680 with Prime Factorization

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

2 x 769 x 409 x 521 x 340 = 111428499880

Therefore, the lowest common multiple of 769,818,521,680 is 111428499880.

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.

769 x 818 x 521 x 680 = 222856999760

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.

769 : 1, 769

818 : 1, 2, 409, 818

521 : 1, 521

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,818,521,680, is 1.

Now, the common factors can be found like this.

769:769

818:2x 409

521:521

680:2x 2x 2x 5x 17

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 = 222856999760/(1x2)

LCM = 222856999760/2

LCM = 111428499880

Thus, we can understand that the LCM of 769,818,521,680 is 111428499880.
