Given numbers are 764,921,247,242

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

The LCM of 764,921,247,242 is 21029808228.

Find LCM of 764,921,247,242 with Prime Factorization

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

2 x 382 x 921 x 247 x 121 = 21029808228

Therefore, the lowest common multiple of 764,921,247,242 is 21029808228.

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.

764 x 921 x 247 x 242 = 42059616456

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.

764 : 1, 2, 4, 191, 382, 764

921 : 1, 3, 307, 921

247 : 1, 13, 19, 247

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,921,247,242, is 1.

Now, the common factors can be found like this.

764:2x 2x 191

921:3x 307

247:13x 19

242:2x 11x 11

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42059616456/(1x2)

LCM = 42059616456/2

LCM = 21029808228

Thus, we can understand that the LCM of 764,921,247,242 is 21029808228.
