Calculate the LCM of 768,700,115,685

Given numbers are 768,700,115,685

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

The LCM of 768,700,115,685 is 423494400.

Find LCM of 768,700,115,685 with Prime Factorization


2 768, 700, 115, 685
2 384, 350, 115, 685
5 192, 175, 115, 685
192, 35, 23, 137

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

2 x 2 x 5 x 192 x 35 x 23 x 137 = 423494400

Therefore, the lowest common multiple of 768,700,115,685 is 423494400.

LCM Formula to Find Lowest Common Multiple of 768,700,115,685

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.

768 x 700 x 115 x 685 = 42349440000

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

115 : 1, 5, 23, 115

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,700,115,685, is 1.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

700:2x 2x 5x 5x 7

115:5x 23

685:5x 137

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 42349440000/(1x100)

LCM = 42349440000/100

LCM = 423494400

Thus, we can understand that the LCM of 768,700,115,685 is 423494400.
