Calculate the LCM of 987,673,779,779,919

Given numbers are 987,673,779,779,919

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

The LCM of 987,673,779,779,919 is 475537955151.

Find LCM of 987,673,779,779,919 with Prime Factorization


19 987, 673, 779, 779, 919
41 987, 673, 41, 41, 919
987, 673, 1, 1, 919

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

19 x 41 x 987 x 673 x 1 x 1 x 919 = 475537955151

Therefore, the lowest common multiple of 987,673,779,779,919 is 475537955151.

LCM Formula to Find Lowest Common Multiple of 987,673,779,779,919

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.

987 x 673 x 779 x 779 x 919 = 370444067062629

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

673 : 1, 673

779 : 1, 19, 41, 779

779 : 1, 19, 41, 779

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,673,779,779,919, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

673:673

779:19x 41

779:19x 41

919:919

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

19x 41 = 779

Therefore, the value for common factors is 779.

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 = 370444067062629/(1x779)

LCM = 370444067062629/779

LCM = 475537955151

Thus, we can understand that the LCM of 987,673,779,779,919 is 475537955151.
