Calculate the LCM of 931,742,655,760

Given numbers are 931,742,655,760

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

The LCM of 931,742,655,760 is 258557320.

Find LCM of 931,742,655,760 with Prime Factorization


2 931, 742, 655, 760
5 931, 371, 655, 380
7 931, 371, 131, 76
19 133, 53, 131, 76
7, 53, 131, 4

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

2 x 5 x 7 x 19 x 7 x 53 x 131 x 4 = 258557320

Therefore, the lowest common multiple of 931,742,655,760 is 258557320.

LCM Formula to Find Lowest Common Multiple of 931,742,655,760

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.

931 x 742 x 655 x 760 = 343881235600

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.

931 : 1, 7, 19, 49, 133, 931

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

655 : 1, 5, 131, 655

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,742,655,760, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

742:2x 7x 53

655:5x 131

760:2x 2x 2x 5x 19

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

2x 5x 7x 19 = 1330

Therefore, the value for common factors is 1330.

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 = 343881235600/(1x1330)

LCM = 343881235600/1330

LCM = 258557320

Thus, we can understand that the LCM of 931,742,655,760 is 258557320.
