Given numbers are 993,973,278,639

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

The LCM of 993,973,278,639 is 411596514.

Find LCM of 993,973,278,639 with Prime Factorization

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

3 x 139 x 331 x 7 x 2 x 213 = 411596514

Therefore, the lowest common multiple of 993,973,278,639 is 411596514.

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.

993 x 973 x 278 x 639 = 171635746338

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.

993 : 1, 3, 331, 993

973 : 1, 7, 139, 973

278 : 1, 2, 139, 278

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,973,278,639, is 1.

Now, the common factors can be found like this.

993:3x 331

973:7x 139

278:2x 139

639:3x 3x 71

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

3x 139 = 417

Therefore, the value for common factors is 417.

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 = 171635746338/(1x417)

LCM = 171635746338/417

LCM = 411596514

Thus, we can understand that the LCM of 993,973,278,639 is 411596514.
