Given numbers are 434,102,979,178

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

The LCM of 434,102,979,178 is 21669186.

Find LCM of 434,102,979,178 with Prime Factorization

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

2 x 89 x 217 x 51 x 11 x 1 = 21669186

Therefore, the lowest common multiple of 434,102,979,178 is 21669186.

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.

434 x 102 x 979 x 178 = 7714230216

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

102 : 1, 2, 3, 6, 17, 34, 51, 102

979 : 1, 11, 89, 979

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,102,979,178, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

102:2x 3x 17

979:11x 89

178:2x 89

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

2x 2x 89 = 356

Therefore, the value for common factors is 356.

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 = 7714230216/(1x356)

LCM = 7714230216/356

LCM = 21669186

Thus, we can understand that the LCM of 434,102,979,178 is 21669186.
