Given numbers are 402,874,970

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

The LCM of 402,874,970 is 85201890.

Find LCM of 402,874,970 with Prime Factorization

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

2 x 201 x 437 x 485 = 85201890

Therefore, the lowest common multiple of 402,874,970 is 85201890.

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.

402 x 874 x 970 = 340807560

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

874 : 1, 2, 19, 23, 38, 46, 437, 874

970 : 1, 2, 5, 10, 97, 194, 485, 970

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,874,970, is 2.

Now, the common factors can be found like this.

402:2x 3x 67

874:2x 19x 23

970:2x 5x 97

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 = 340807560/(2x2)

LCM = 340807560/4

LCM = 85201890

Thus, we can understand that the LCM of 402,874,970 is 85201890.
