Given numbers are 938,643,104,804,247

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

The LCM of 938,643,104,804,247 is 1787689176.

Find LCM of 938,643,104,804,247 with Prime Factorization

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

2 x 2 x 13 x 67 x 7 x 643 x 2 x 3 x 19 = 1787689176

Therefore, the lowest common multiple of 938,643,104,804,247 is 1787689176.

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.

938 x 643 x 104 x 804 x 247 = 12456618178368

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

643 : 1, 643

104 : 1, 2, 4, 8, 13, 26, 52, 104

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,643,104,804,247, is 1.

Now, the common factors can be found like this.

938:2x 7x 67

643:643

104:2x 2x 2x 13

804:2x 2x 3x 67

247:13x 19

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

2x 2x 2x 13x 67 = 6968

Therefore, the value for common factors is 6968.

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 = 12456618178368/(1x6968)

LCM = 12456618178368/6968

LCM = 1787689176

Thus, we can understand that the LCM of 938,643,104,804,247 is 1787689176.
