Calculate the LCM of 815,390,973,241,777

Given numbers are 815,390,973,241,777

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

The LCM of 815,390,973,241,777 is 551548640370.

Find LCM of 815,390,973,241,777 with Prime Factorization


3 815, 390, 973, 241, 777
5 815, 130, 973, 241, 259
7 163, 26, 973, 241, 259
163, 26, 139, 241, 37

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

3 x 5 x 7 x 163 x 26 x 139 x 241 x 37 = 551548640370

Therefore, the lowest common multiple of 815,390,973,241,777 is 551548640370.

LCM Formula to Find Lowest Common Multiple of 815,390,973,241,777

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.

815 x 390 x 973 x 241 x 777 = 57912607238850

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.

815 : 1, 5, 163, 815

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

973 : 1, 7, 139, 973

241 : 1, 241

777 : 1, 3, 7, 21, 37, 111, 259, 777

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,390,973,241,777, is 1.

Now, the common factors can be found like this.

815:5x 163

390:2x 3x 5x 13

973:7x 139

241:241

777:3x 7x 37

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

3x 5x 7 = 105

Therefore, the value for common factors is 105.

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 = 57912607238850/(1x105)

LCM = 57912607238850/105

LCM = 551548640370

Thus, we can understand that the LCM of 815,390,973,241,777 is 551548640370.
