Given numbers are 998,739,420

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

The LCM of 998,739,420 is 154879620.

Find LCM of 998,739,420 with Prime Factorization

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

2 x 499 x 739 x 210 = 154879620

Therefore, the lowest common multiple of 998,739,420 is 154879620.

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.

998 x 739 x 420 = 309759240

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.

998 : 1, 2, 499, 998

739 : 1, 739

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,739,420, is 1.

Now, the common factors can be found like this.

998:2x 499

739:739

420:2x 2x 3x 5x 7

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 = 309759240/(1x2)

LCM = 309759240/2

LCM = 154879620

Thus, we can understand that the LCM of 998,739,420 is 154879620.
