Calculate the LCM of 724,117,821,821

Given numbers are 724,117,821,821

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

The LCM of 724,117,821,821 is 69545268.

Find LCM of 724,117,821,821 with Prime Factorization


821 724, 117, 821, 821
724, 117, 1, 1

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

821 x 724 x 117 x 1 x 1 = 69545268

Therefore, the lowest common multiple of 724,117,821,821 is 69545268.

LCM Formula to Find Lowest Common Multiple of 724,117,821,821

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.

724 x 117 x 821 x 821 = 57096665028

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.

724 : 1, 2, 4, 181, 362, 724

117 : 1, 3, 9, 13, 39, 117

821 : 1, 821

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,117,821,821, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

117:3x 3x 13

821:821

821:821

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

821 = 821

Therefore, the value for common factors is 821.

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 = 57096665028/(1x821)

LCM = 57096665028/821

LCM = 69545268

Thus, we can understand that the LCM of 724,117,821,821 is 69545268.
