Given numbers are 370,643,538

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

The LCM of 370,643,538 is 63997790.

Find LCM of 370,643,538 with Prime Factorization

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

2 x 185 x 643 x 269 = 63997790

Therefore, the lowest common multiple of 370,643,538 is 63997790.

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.

370 x 643 x 538 = 127995580

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.

370 : 1, 2, 5, 10, 37, 74, 185, 370

643 : 1, 643

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 370,643,538, is 1.

Now, the common factors can be found like this.

370:2x 5x 37

643:643

538:2x 269

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 = 127995580/(1x2)

LCM = 127995580/2

LCM = 63997790

Thus, we can understand that the LCM of 370,643,538 is 63997790.

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

• LCM of 878, 643, 468
• LCM of 140, 454, 950
