Given numbers are 247,794,147,560

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

The LCM of 247,794,147,560 is 1153173840.

Find LCM of 247,794,147,560 with Prime Factorization

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

2 x 7 x 247 x 397 x 21 x 40 = 1153173840

Therefore, the lowest common multiple of 247,794,147,560 is 1153173840.

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.

247 x 794 x 147 x 560 = 16144433760

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.

247 : 1, 13, 19, 247

794 : 1, 2, 397, 794

147 : 1, 3, 7, 21, 49, 147

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,794,147,560, is 1.

Now, the common factors can be found like this.

247:13x 19

794:2x 397

147:3x 7x 7

560:2x 2x 2x 2x 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 7 = 14

Therefore, the value for common factors is 14.

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 = 16144433760/(1x14)

LCM = 16144433760/14

LCM = 1153173840

Thus, we can understand that the LCM of 247,794,147,560 is 1153173840.
