Given numbers are 782,688,129,812

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

The LCM of 782,688,129,812 is 163825872.

Find LCM of 782,688,129,812 with Prime Factorization

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

2 x 2 x 43 x 391 x 4 x 3 x 203 = 163825872

Therefore, the lowest common multiple of 782,688,129,812 is 163825872.

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.

782 x 688 x 129 x 812 = 56356099968

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

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

129 : 1, 3, 43, 129

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,688,129,812, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

688:2x 2x 2x 2x 43

129:3x 43

812:2x 2x 7x 29

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 43 = 344

Therefore, the value for common factors is 344.

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 = 56356099968/(1x344)

LCM = 56356099968/344

LCM = 163825872

Thus, we can understand that the LCM of 782,688,129,812 is 163825872.
