Calculate the LCM of 774,420,464,841

Given numbers are 774,420,464,841

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

The LCM of 774,420,464,841 is 182261520.

Find LCM of 774,420,464,841 with Prime Factorization


2 774, 420, 464, 841
2 387, 210, 232, 841
3 387, 105, 116, 841
29 129, 35, 116, 841
129, 35, 4, 29

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

2 x 2 x 3 x 29 x 129 x 35 x 4 x 29 = 182261520

Therefore, the lowest common multiple of 774,420,464,841 is 182261520.

LCM Formula to Find Lowest Common Multiple of 774,420,464,841

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.

774 x 420 x 464 x 841 = 126854017920

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,420,464,841, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

420:2x 2x 3x 5x 7

464:2x 2x 2x 2x 29

841:29x 29

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 3x 29 = 696

Therefore, the value for common factors is 696.

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 = 126854017920/(1x696)

LCM = 126854017920/696

LCM = 182261520

Thus, we can understand that the LCM of 774,420,464,841 is 182261520.
