Given numbers are 674,921,214,428

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

The LCM of 674,921,214,428 is 132841356.

Find LCM of 674,921,214,428 with Prime Factorization

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

2 x 107 x 337 x 921 x 1 x 2 = 132841356

Therefore, the lowest common multiple of 674,921,214,428 is 132841356.

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.

674 x 921 x 214 x 428 = 56856100368

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.

674 : 1, 2, 337, 674

921 : 1, 3, 307, 921

214 : 1, 2, 107, 214

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,921,214,428, is 1.

Now, the common factors can be found like this.

674:2x 337

921:3x 307

214:2x 107

428:2x 2x 107

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 107 = 428

Therefore, the value for common factors is 428.

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 = 56856100368/(1x428)

LCM = 56856100368/428

LCM = 132841356

Thus, we can understand that the LCM of 674,921,214,428 is 132841356.
