Given numbers are 177,202,666,721

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

The LCM of 177,202,666,721 is 2861428374.

Find LCM of 177,202,666,721 with Prime Factorization

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

2 x 3 x 59 x 101 x 111 x 721 = 2861428374

Therefore, the lowest common multiple of 177,202,666,721 is 2861428374.

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.

177 x 202 x 666 x 721 = 17168570244

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.

177 : 1, 3, 59, 177

202 : 1, 2, 101, 202

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,202,666,721, is 1.

Now, the common factors can be found like this.

177:3x 59

202:2x 101

666:2x 3x 3x 37

721:7x 103

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 17168570244/(1x6)

LCM = 17168570244/6

LCM = 2861428374

Thus, we can understand that the LCM of 177,202,666,721 is 2861428374.
