Given numbers are 647,341,155,387

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

The LCM of 647,341,155,387 is 426913245.

Find LCM of 647,341,155,387 with Prime Factorization

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

31 x 647 x 11 x 5 x 387 = 426913245

Therefore, the lowest common multiple of 647,341,155,387 is 426913245.

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.

647 x 341 x 155 x 387 = 13234310595

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.

647 : 1, 647

341 : 1, 11, 31, 341

155 : 1, 5, 31, 155

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,341,155,387, is 1.

Now, the common factors can be found like this.

647:647

341:11x 31

155:5x 31

387:3x 3x 43

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

31 = 31

Therefore, the value for common factors is 31.

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 = 13234310595/(1x31)

LCM = 13234310595/31

LCM = 426913245

Thus, we can understand that the LCM of 647,341,155,387 is 426913245.
