Given numbers are 7,977,538,812

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

The LCM of 7,977,538,812 is 213404156.

Find LCM of 7,977,538,812 with Prime Factorization

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

2 x 7 x 1 x 977 x 269 x 58 = 213404156

Therefore, the lowest common multiple of 7,977,538,812 is 213404156.

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.

7 x 977 x 538 x 812 = 2987658184

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.

7 : 1, 7

977 : 1, 977

538 : 1, 2, 269, 538

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,977,538,812, is 1.

Now, the common factors can be found like this.

7:7

977:977

538:2x 269

812:2x 2x 7x 29

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 2987658184/(1x14)

LCM = 2987658184/14

LCM = 213404156

Thus, we can understand that the LCM of 7,977,538,812 is 213404156.
