Calculate the LCM of 721,721,146,633,854

Given numbers are 721,721,146,633,854

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

The LCM of 721,721,146,633,854 is 4064636058.

Find LCM of 721,721,146,633,854 with Prime Factorization


2 721, 721, 146, 633, 854
7 721, 721, 73, 633, 427
103 103, 103, 73, 633, 61
1, 1, 73, 633, 61

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

2 x 7 x 103 x 1 x 1 x 73 x 633 x 61 = 4064636058

Therefore, the lowest common multiple of 721,721,146,633,854 is 4064636058.

LCM Formula to Find Lowest Common Multiple of 721,721,146,633,854

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 721 x 146 x 633 x 854 = 41028436369452

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

721 : 1, 7, 103, 721

146 : 1, 2, 73, 146

633 : 1, 3, 211, 633

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,721,146,633,854, is 1.

Now, the common factors can be found like this.

721:7x 103

721:7x 103

146:2x 73

633:3x 211

854:2x 7x 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 7x 103 = 10094

Therefore, the value for common factors is 10094.

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 = 41028436369452/(1x10094)

LCM = 41028436369452/10094

LCM = 4064636058

Thus, we can understand that the LCM of 721,721,146,633,854 is 4064636058.
