Calculate the LCM of 803,421,365,191,668

Given numbers are 803,421,365,191,668

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

The LCM of 803,421,365,191,668 is 215663910220.

Find LCM of 803,421,365,191,668 with Prime Factorization


73 803, 421, 365, 191, 668
11, 421, 5, 191, 668

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

73 x 11 x 421 x 5 x 191 x 668 = 215663910220

Therefore, the lowest common multiple of 803,421,365,191,668 is 215663910220.

LCM Formula to Find Lowest Common Multiple of 803,421,365,191,668

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.

803 x 421 x 365 x 191 x 668 = 15743465446060

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.

803 : 1, 11, 73, 803

421 : 1, 421

365 : 1, 5, 73, 365

191 : 1, 191

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,421,365,191,668, is 1.

Now, the common factors can be found like this.

803:11x 73

421:421

365:5x 73

191:191

668:2x 2x 167

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

73 = 73

Therefore, the value for common factors is 73.

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 = 15743465446060/(1x73)

LCM = 15743465446060/73

LCM = 215663910220

Thus, we can understand that the LCM of 803,421,365,191,668 is 215663910220.
