Given numbers are 706,170,553,642

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

The LCM of 706,170,553,642 is 10652555130.

Find LCM of 706,170,553,642 with Prime Factorization

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

2 x 353 x 85 x 553 x 321 = 10652555130

Therefore, the lowest common multiple of 706,170,553,642 is 10652555130.

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.

706 x 170 x 553 x 642 = 42610220520

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.

706 : 1, 2, 353, 706

170 : 1, 2, 5, 10, 17, 34, 85, 170

553 : 1, 7, 79, 553

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,170,553,642, is 1.

Now, the common factors can be found like this.

706:2x 353

170:2x 5x 17

553:7x 79

642:2x 3x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 42610220520/(1x4)

LCM = 42610220520/4

LCM = 10652555130

Thus, we can understand that the LCM of 706,170,553,642 is 10652555130.
