Given numbers are 78,487,974

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

The LCM of 78,487,974 is 37986.

Find LCM of 78,487,974 with Prime Factorization

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

2 x 487 x 39 x 1 x 1 = 37986

Therefore, the lowest common multiple of 78,487,974 is 37986.

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.

78 x 487 x 974 = 36998364

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.

78 : 1, 2, 3, 6, 13, 26, 39, 78

487 : 1, 487

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 78,487,974, is 1.

Now, the common factors can be found like this.

78:2x 3x 13

487:487

974:2x 487

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

2x 487 = 974

Therefore, the value for common factors is 974.

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 = 36998364/(1x974)

LCM = 36998364/974

LCM = 37986

Thus, we can understand that the LCM of 78,487,974 is 37986.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 23, 711, 566
• LCM of 42, 691, 609
