Calculate the LCM of 721,223,794,553,772

Given numbers are 721,223,794,553,772

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

The LCM of 721,223,794,553,772 is 3892915940788.

Find LCM of 721,223,794,553,772 with Prime Factorization


2 721, 223, 794, 553, 772
7 721, 223, 397, 553, 386
103, 223, 397, 79, 386

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

2 x 7 x 103 x 223 x 397 x 79 x 386 = 3892915940788

Therefore, the lowest common multiple of 721,223,794,553,772 is 3892915940788.

LCM Formula to Find Lowest Common Multiple of 721,223,794,553,772

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.

721 x 223 x 794 x 553 x 772 = 54500823171032

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.

721 : 1, 7, 103, 721

223 : 1, 223

794 : 1, 2, 397, 794

553 : 1, 7, 79, 553

772 : 1, 2, 4, 193, 386, 772

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,223,794,553,772, is 1.

Now, the common factors can be found like this.

721:7x 103

223:223

794:2x 397

553:7x 79

772:2x 2x 193

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 54500823171032/(1x14)

LCM = 54500823171032/14

LCM = 3892915940788

Thus, we can understand that the LCM of 721,223,794,553,772 is 3892915940788.
