Calculate the LCM of 981,181,779,697

Given numbers are 981,181,779,697

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

The LCM of 981,181,779,697 is 2351440323.

Find LCM of 981,181,779,697 with Prime Factorization


41 981, 181, 779, 697
981, 181, 19, 17

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

41 x 981 x 181 x 19 x 17 = 2351440323

Therefore, the lowest common multiple of 981,181,779,697 is 2351440323.

LCM Formula to Find Lowest Common Multiple of 981,181,779,697

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.

981 x 181 x 779 x 697 = 96409053243

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.

981 : 1, 3, 9, 109, 327, 981

181 : 1, 181

779 : 1, 19, 41, 779

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,181,779,697, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

181:181

779:19x 41

697:17x 41

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

41 = 41

Therefore, the value for common factors is 41.

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 = 96409053243/(1x41)

LCM = 96409053243/41

LCM = 2351440323

Thus, we can understand that the LCM of 981,181,779,697 is 2351440323.
