Calculate the LCM of 751,979,778,940

Given numbers are 751,979,778,940

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

The LCM of 751,979,778,940 is 268843836140.

Find LCM of 751,979,778,940 with Prime Factorization


2 751, 979, 778, 940
751, 979, 389, 470

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

2 x 751 x 979 x 389 x 470 = 268843836140

Therefore, the lowest common multiple of 751,979,778,940 is 268843836140.

LCM Formula to Find Lowest Common Multiple of 751,979,778,940

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.

751 x 979 x 778 x 940 = 537687672280

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.

751 : 1, 751

979 : 1, 11, 89, 979

778 : 1, 2, 389, 778

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,979,778,940, is 1.

Now, the common factors can be found like this.

751:751

979:11x 89

778:2x 389

940:2x 2x 5x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 537687672280/(1x2)

LCM = 537687672280/2

LCM = 268843836140

Thus, we can understand that the LCM of 751,979,778,940 is 268843836140.
