Given numbers are 690,158,424,919

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

The LCM of 690,158,424,919 is 10620074280.

Find LCM of 690,158,424,919 with Prime Factorization

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

2 x 345 x 79 x 212 x 919 = 10620074280

Therefore, the lowest common multiple of 690,158,424,919 is 10620074280.

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.

690 x 158 x 424 x 919 = 42480297120

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

158 : 1, 2, 79, 158

424 : 1, 2, 4, 8, 53, 106, 212, 424

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,158,424,919, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

158:2x 79

424:2x 2x 2x 53

919:919

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 42480297120/(1x4)

LCM = 42480297120/4

LCM = 10620074280

Thus, we can understand that the LCM of 690,158,424,919 is 10620074280.
