Calculate the LCM of 391,493,723,724

Given numbers are 391,493,723,724

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

The LCM of 391,493,723,724 is 5935422228.

Find LCM of 391,493,723,724 with Prime Factorization


17 391, 493, 723, 724
23, 29, 723, 724

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

17 x 23 x 29 x 723 x 724 = 5935422228

Therefore, the lowest common multiple of 391,493,723,724 is 5935422228.

LCM Formula to Find Lowest Common Multiple of 391,493,723,724

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.

391 x 493 x 723 x 724 = 100902177876

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.

391 : 1, 17, 23, 391

493 : 1, 17, 29, 493

723 : 1, 3, 241, 723

724 : 1, 2, 4, 181, 362, 724

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,493,723,724, is 1.

Now, the common factors can be found like this.

391:17x 23

493:17x 29

723:3x 241

724:2x 2x 181

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

17 = 17

Therefore, the value for common factors is 17.

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 = 100902177876/(1x17)

LCM = 100902177876/17

LCM = 5935422228

Thus, we can understand that the LCM of 391,493,723,724 is 5935422228.
