Calculate the LCM of 721,715,882,782,793

Given numbers are 721,715,882,782,793

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

The LCM of 721,715,882,782,793 is 1549239081390.

Find LCM of 721,715,882,782,793 with Prime Factorization


2 721, 715, 882, 782, 793
7 721, 715, 441, 391, 793
13 103, 715, 63, 391, 793
103, 55, 63, 391, 61

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

2 x 7 x 13 x 103 x 55 x 63 x 391 x 61 = 1549239081390

Therefore, the lowest common multiple of 721,715,882,782,793 is 1549239081390.

LCM Formula to Find Lowest Common Multiple of 721,715,882,782,793

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 715 x 882 x 782 x 793 = 281961512812980

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

782 : 1, 2, 17, 23, 34, 46, 391, 782

793 : 1, 13, 61, 793

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,715,882,782,793, is 1.

Now, the common factors can be found like this.

721:7x 103

715:5x 11x 13

882:2x 3x 3x 7x 7

782:2x 17x 23

793:13x 61

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

2x 7x 13 = 182

Therefore, the value for common factors is 182.

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 = 281961512812980/(1x182)

LCM = 281961512812980/182

LCM = 1549239081390

Thus, we can understand that the LCM of 721,715,882,782,793 is 1549239081390.
