Calculate the LCM of 915,721,427,967

Given numbers are 915,721,427,967

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

The LCM of 915,721,427,967 is 637944405.

Find LCM of 915,721,427,967 with Prime Factorization


7 915, 721, 427, 967
61 915, 103, 61, 967
15, 103, 1, 967

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

7 x 61 x 15 x 103 x 1 x 967 = 637944405

Therefore, the lowest common multiple of 915,721,427,967 is 637944405.

LCM Formula to Find Lowest Common Multiple of 915,721,427,967

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.

915 x 721 x 427 x 967 = 272402260935

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

721 : 1, 7, 103, 721

427 : 1, 7, 61, 427

967 : 1, 967

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,721,427,967, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

721:7x 103

427:7x 61

967:967

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

7x 61 = 427

Therefore, the value for common factors is 427.

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 = 272402260935/(1x427)

LCM = 272402260935/427

LCM = 637944405

Thus, we can understand that the LCM of 915,721,427,967 is 637944405.
