Given numbers are 221,909,199,707

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

The LCM of 221,909,199,707 is 279838377.

Find LCM of 221,909,199,707 with Prime Factorization

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

101 x 221 x 9 x 199 x 7 = 279838377

Therefore, the lowest common multiple of 221,909,199,707 is 279838377.

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.

221 x 909 x 199 x 707 = 28263676077

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.

221 : 1, 13, 17, 221

909 : 1, 3, 9, 101, 303, 909

199 : 1, 199

707 : 1, 7, 101, 707

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,909,199,707, is 1.

Now, the common factors can be found like this.

221:13x 17

909:3x 3x 101

199:199

707:7x 101

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

101 = 101

Therefore, the value for common factors is 101.

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 = 28263676077/(1x101)

LCM = 28263676077/101

LCM = 279838377

Thus, we can understand that the LCM of 221,909,199,707 is 279838377.
