Given numbers are 713,840,688,205

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

The LCM of 713,840,688,205 is 2111791920.

Find LCM of 713,840,688,205 with Prime Factorization

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

2 x 2 x 2 x 5 x 713 x 21 x 86 x 41 = 2111791920

Therefore, the lowest common multiple of 713,840,688,205 is 2111791920.

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.

713 x 840 x 688 x 205 = 84471676800

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.

713 : 1, 23, 31, 713

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,840,688,205, is 1.

Now, the common factors can be found like this.

713:23x 31

840:2x 2x 2x 3x 5x 7

688:2x 2x 2x 2x 43

205:5x 41

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

2x 2x 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 84471676800/(1x40)

LCM = 84471676800/40

LCM = 2111791920

Thus, we can understand that the LCM of 713,840,688,205 is 2111791920.
