Given numbers are 378,977,977,790

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

The LCM of 378,977,977,790 is 145875870.

Find LCM of 378,977,977,790 with Prime Factorization

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

2 x 977 x 189 x 1 x 1 x 395 = 145875870

Therefore, the lowest common multiple of 378,977,977,790 is 145875870.

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.

378 x 977 x 977 x 790 = 285041449980

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.

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

977 : 1, 977

977 : 1, 977

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,977,977,790, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

977:977

977:977

790:2x 5x 79

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

2x 977 = 1954

Therefore, the value for common factors is 1954.

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 = 285041449980/(1x1954)

LCM = 285041449980/1954

LCM = 145875870

Thus, we can understand that the LCM of 378,977,977,790 is 145875870.
