Calculate the LCM of 426,137,680,842

Given numbers are 426,137,680,842

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

The LCM of 426,137,680,842 is 8353936680.

Find LCM of 426,137,680,842 with Prime Factorization


2 426, 137, 680, 842
213, 137, 340, 421

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

2 x 213 x 137 x 340 x 421 = 8353936680

Therefore, the lowest common multiple of 426,137,680,842 is 8353936680.

LCM Formula to Find Lowest Common Multiple of 426,137,680,842

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.

426 x 137 x 680 x 842 = 33415746720

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

137 : 1, 137

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,137,680,842, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

137:137

680:2x 2x 2x 5x 17

842:2x 421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 33415746720/(1x4)

LCM = 33415746720/4

LCM = 8353936680

Thus, we can understand that the LCM of 426,137,680,842 is 8353936680.
