Given numbers are 709,805,247,161

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

The LCM of 709,805,247,161 is 140974015.

Find LCM of 709,805,247,161 with Prime Factorization

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

7 x 23 x 709 x 5 x 247 x 1 = 140974015

Therefore, the lowest common multiple of 709,805,247,161 is 140974015.

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.

709 x 805 x 247 x 161 = 22696816415

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.

709 : 1, 709

805 : 1, 5, 7, 23, 35, 115, 161, 805

247 : 1, 13, 19, 247

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,805,247,161, is 1.

Now, the common factors can be found like this.

709:709

805:5x 7x 23

247:13x 19

161:7x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 22696816415/(1x161)

LCM = 22696816415/161

LCM = 140974015

Thus, we can understand that the LCM of 709,805,247,161 is 140974015.
