Given numbers are 643,438,254,127

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

The LCM of 643,438,254,127 is 35767518.

Find LCM of 643,438,254,127 with Prime Factorization

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

2 x 127 x 643 x 219 x 1 x 1 = 35767518

Therefore, the lowest common multiple of 643,438,254,127 is 35767518.

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.

643 x 438 x 254 x 127 = 9084949572

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.

643 : 1, 643

438 : 1, 2, 3, 6, 73, 146, 219, 438

254 : 1, 2, 127, 254

127 : 1, 127

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,438,254,127, is 1.

Now, the common factors can be found like this.

643:643

438:2x 3x 73

254:2x 127

127:127

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 9084949572/(1x254)

LCM = 9084949572/254

LCM = 35767518

Thus, we can understand that the LCM of 643,438,254,127 is 35767518.

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

• LCM of 674, 365, 368, 432
