Given numbers are 549,303,974,420

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

The LCM of 549,303,974,420 is 3780512820.

Find LCM of 549,303,974,420 with Prime Factorization

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

2 x 3 x 183 x 101 x 487 x 70 = 3780512820

Therefore, the lowest common multiple of 549,303,974,420 is 3780512820.

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.

549 x 303 x 974 x 420 = 68049230760

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.

549 : 1, 3, 9, 61, 183, 549

303 : 1, 3, 101, 303

974 : 1, 2, 487, 974

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 549,303,974,420, is 1.

Now, the common factors can be found like this.

549:3x 3x 61

303:3x 101

974:2x 487

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.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 68049230760/(1x18)

LCM = 68049230760/18

LCM = 3780512820

Thus, we can understand that the LCM of 549,303,974,420 is 3780512820.
