Calculate the LCM of 720,841,841,518

Given numbers are 720,841,841,518

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

The LCM of 720,841,841,518 is 156829680.

Find LCM of 720,841,841,518 with Prime Factorization


2 720, 841, 841, 518
29 360, 841, 841, 259
29 360, 29, 29, 259
360, 1, 1, 259

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

2 x 29 x 29 x 360 x 1 x 1 x 259 = 156829680

Therefore, the lowest common multiple of 720,841,841,518 is 156829680.

LCM Formula to Find Lowest Common Multiple of 720,841,841,518

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.

720 x 841 x 841 x 518 = 263787521760

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

841 : 1, 29, 841

841 : 1, 29, 841

518 : 1, 2, 7, 14, 37, 74, 259, 518

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,841,841,518, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

841:29x 29

841:29x 29

518:2x 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.

2x 29x 29 = 1682

Therefore, the value for common factors is 1682.

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 = 263787521760/(1x1682)

LCM = 263787521760/1682

LCM = 156829680

Thus, we can understand that the LCM of 720,841,841,518 is 156829680.
