Given numbers are 161,688,876,769

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

The LCM of 161,688,876,769 is 18654549648.

Find LCM of 161,688,876,769 with Prime Factorization

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

2 x 2 x 161 x 172 x 219 x 769 = 18654549648

Therefore, the lowest common multiple of 161,688,876,769 is 18654549648.

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.

161 x 688 x 876 x 769 = 74618198592

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.

161 : 1, 7, 23, 161

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

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,688,876,769, is 1.

Now, the common factors can be found like this.

161:7x 23

688:2x 2x 2x 2x 43

876:2x 2x 3x 73

769:769

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 74618198592/(1x4)

LCM = 74618198592/4

LCM = 18654549648

Thus, we can understand that the LCM of 161,688,876,769 is 18654549648.
