Calculate the LCM of 820,616,754,682

Given numbers are 820,616,754,682

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

The LCM of 820,616,754,682 is 1475834360.

Find LCM of 820,616,754,682 with Prime Factorization


2 820, 616, 754, 682
2 410, 308, 377, 341
11 205, 154, 377, 341
205, 14, 377, 31

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

2 x 2 x 11 x 205 x 14 x 377 x 31 = 1475834360

Therefore, the lowest common multiple of 820,616,754,682 is 1475834360.

LCM Formula to Find Lowest Common Multiple of 820,616,754,682

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.

820 x 616 x 754 x 682 = 259746847360

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

754 : 1, 2, 13, 26, 29, 58, 377, 754

682 : 1, 2, 11, 22, 31, 62, 341, 682

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,616,754,682, is 2.

Now, the common factors can be found like this.

820:2x 2x 5x 41

616:2x 2x 2x 7x 11

754:2x 13x 29

682:2x 11x 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 2x 11 = 88

Therefore, the value for common factors is 88.

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 = 259746847360/(2x88)

LCM = 259746847360/176

LCM = 1475834360

Thus, we can understand that the LCM of 820,616,754,682 is 1475834360.
