Given numbers are 208,690,161,641,713

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

The LCM of 208,690,161,641,713 is 9981600720.

Find LCM of 208,690,161,641,713 with Prime Factorization

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

2 x 23 x 104 x 15 x 7 x 641 x 31 = 9981600720

Therefore, the lowest common multiple of 208,690,161,641,713 is 9981600720.

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.

208 x 690 x 161 x 641 x 713 = 10560533561760

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.

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

161 : 1, 7, 23, 161

641 : 1, 641

713 : 1, 23, 31, 713

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,690,161,641,713, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

690:2x 3x 5x 23

161:7x 23

641:641

713:23x 31

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

2x 23x 23 = 1058

Therefore, the value for common factors is 1058.

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 = 10560533561760/(1x1058)

LCM = 10560533561760/1058

LCM = 9981600720

Thus, we can understand that the LCM of 208,690,161,641,713 is 9981600720.
