Given numbers are 762,190,821,860

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

The LCM of 762,190,821,860 is 5111168340.

Find LCM of 762,190,821,860 with Prime Factorization

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

2 x 5 x 381 x 19 x 821 x 86 = 5111168340

Therefore, the lowest common multiple of 762,190,821,860 is 5111168340.

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.

762 x 190 x 821 x 860 = 102223366800

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.

762 : 1, 2, 3, 6, 127, 254, 381, 762

190 : 1, 2, 5, 10, 19, 38, 95, 190

821 : 1, 821

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,190,821,860, is 1.

Now, the common factors can be found like this.

762:2x 3x 127

190:2x 5x 19

821:821

860:2x 2x 5x 43

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 102223366800/(1x20)

LCM = 102223366800/20

LCM = 5111168340

Thus, we can understand that the LCM of 762,190,821,860 is 5111168340.
