Calculate the LCM of 781,568,837,160

Given numbers are 781,568,837,160

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

The LCM of 781,568,837,160 is 104591520.

Find LCM of 781,568,837,160 with Prime Factorization


2 781, 568, 837, 160
2 781, 284, 837, 80
2 781, 142, 837, 40
71 781, 71, 837, 20
11, 1, 837, 20

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

2 x 2 x 2 x 71 x 11 x 1 x 837 x 20 = 104591520

Therefore, the lowest common multiple of 781,568,837,160 is 104591520.

LCM Formula to Find Lowest Common Multiple of 781,568,837,160

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.

781 x 568 x 837 x 160 = 59407983360

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.

781 : 1, 11, 71, 781

568 : 1, 2, 4, 8, 71, 142, 284, 568

837 : 1, 3, 9, 27, 31, 93, 279, 837

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,568,837,160, is 1.

Now, the common factors can be found like this.

781:11x 71

568:2x 2x 2x 71

837:3x 3x 3x 31

160:2x 2x 2x 2x 2x 5

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 2x 71 = 568

Therefore, the value for common factors is 568.

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 = 59407983360/(1x568)

LCM = 59407983360/568

LCM = 104591520

Thus, we can understand that the LCM of 781,568,837,160 is 104591520.
