Calculate the LCM of 788,901,831,742,940

Given numbers are 788,901,831,742,940

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

The LCM of 788,901,831,742,940 is 970550046060.

Find LCM of 788,901,831,742,940 with Prime Factorization


2 788, 901, 831, 742, 940
2 394, 901, 831, 371, 470
53 197, 901, 831, 371, 235
197, 17, 831, 7, 235

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

2 x 2 x 53 x 197 x 17 x 831 x 7 x 235 = 970550046060

Therefore, the lowest common multiple of 788,901,831,742,940 is 970550046060.

LCM Formula to Find Lowest Common Multiple of 788,901,831,742,940

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.

788 x 901 x 831 x 742 x 940 = 411513219529440

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.

788 : 1, 2, 4, 197, 394, 788

901 : 1, 17, 53, 901

831 : 1, 3, 277, 831

742 : 1, 2, 7, 14, 53, 106, 371, 742

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 788,901,831,742,940, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

901:17x 53

831:3x 277

742:2x 7x 53

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.

2x 2x 2x 53 = 424

Therefore, the value for common factors is 424.

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 = 411513219529440/(1x424)

LCM = 411513219529440/424

LCM = 970550046060

Thus, we can understand that the LCM of 788,901,831,742,940 is 970550046060.
