Calculate the LCM of 123,744,858,310

Given numbers are 123,744,858,310

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

The LCM of 123,744,858,310 is 21810360.

Find LCM of 123,744,858,310 with Prime Factorization


2 123, 744, 858, 310
3 123, 372, 429, 155
31 41, 124, 143, 155
41, 4, 143, 5

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

2 x 3 x 31 x 41 x 4 x 143 x 5 = 21810360

Therefore, the lowest common multiple of 123,744,858,310 is 21810360.

LCM Formula to Find Lowest Common Multiple of 123,744,858,310

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.

123 x 744 x 858 x 310 = 24340361760

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.

123 : 1, 3, 41, 123

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

310 : 1, 2, 5, 10, 31, 62, 155, 310

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,744,858,310, is 1.

Now, the common factors can be found like this.

123:3x 41

744:2x 2x 2x 3x 31

858:2x 3x 11x 13

310:2x 5x 31

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 3x 3x 31 = 1116

Therefore, the value for common factors is 1116.

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 = 24340361760/(1x1116)

LCM = 24340361760/1116

LCM = 21810360

Thus, we can understand that the LCM of 123,744,858,310 is 21810360.
