Given numbers are 530,642,847

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

The LCM of 530,642,847 is 144100110.

Find LCM of 530,642,847 with Prime Factorization

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

2 x 265 x 321 x 847 = 144100110

Therefore, the lowest common multiple of 530,642,847 is 144100110.

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.

530 x 642 x 847 = 288200220

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.

530 : 1, 2, 5, 10, 53, 106, 265, 530

642 : 1, 2, 3, 6, 107, 214, 321, 642

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,642,847, is 1.

Now, the common factors can be found like this.

530:2x 5x 53

642:2x 3x 107

847:7x 11x 11

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 = 288200220/(1x2)

LCM = 288200220/2

LCM = 144100110

Thus, we can understand that the LCM of 530,642,847 is 144100110.

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

• LCM of 597, 802, 673
