Given numbers are 718,646,219,427

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

The LCM of 718,646,219,427 is 21686973882.

Find LCM of 718,646,219,427 with Prime Factorization

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

2 x 359 x 323 x 219 x 427 = 21686973882

Therefore, the lowest common multiple of 718,646,219,427 is 21686973882.

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.

718 x 646 x 219 x 427 = 43373947764

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.

718 : 1, 2, 359, 718

646 : 1, 2, 17, 19, 34, 38, 323, 646

219 : 1, 3, 73, 219

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,646,219,427, is 1.

Now, the common factors can be found like this.

718:2x 359

646:2x 17x 19

219:3x 73

427:7x 61

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 = 43373947764/(1x2)

LCM = 43373947764/2

LCM = 21686973882

Thus, we can understand that the LCM of 718,646,219,427 is 21686973882.
