Given numbers are 247,691,689,546

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

The LCM of 247,691,689,546 is 379927002.

Find LCM of 247,691,689,546 with Prime Factorization

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

13 x 19 x 691 x 53 x 42 = 379927002

Therefore, the lowest common multiple of 247,691,689,546 is 379927002.

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 691 x 689 x 546 = 64207663338

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

691 : 1, 691

689 : 1, 13, 53, 689

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,691,689,546, is 1.

Now, the common factors can be found like this.

247:13x 19

691:691

689:13x 53

546:2x 3x 7x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 64207663338/(1x169)

LCM = 64207663338/169

LCM = 379927002

Thus, we can understand that the LCM of 247,691,689,546 is 379927002.
