Given numbers are 647,749,702,214,163

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

The LCM of 647,749,702,214,163 is 55451182878.

Find LCM of 647,749,702,214,163 with Prime Factorization

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

2 x 107 x 647 x 7 x 351 x 1 x 163 = 55451182878

Therefore, the lowest common multiple of 647,749,702,214,163 is 55451182878.

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 749 x 702 x 214 x 163 = 11866553135892

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

749 : 1, 7, 107, 749

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

214 : 1, 2, 107, 214

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,749,702,214,163, is 1.

Now, the common factors can be found like this.

647:647

749:7x 107

702:2x 3x 3x 3x 13

214:2x 107

163:163

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 11866553135892/(1x214)

LCM = 11866553135892/214

LCM = 55451182878

Thus, we can understand that the LCM of 647,749,702,214,163 is 55451182878.
