Given numbers are 661,146,421,246

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

The LCM of 661,146,421,246 is 4997370198.

Find LCM of 661,146,421,246 with Prime Factorization

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

2 x 661 x 73 x 421 x 123 = 4997370198

Therefore, the lowest common multiple of 661,146,421,246 is 4997370198.

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.

661 x 146 x 421 x 246 = 9994740396

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.

661 : 1, 661

146 : 1, 2, 73, 146

421 : 1, 421

246 : 1, 2, 3, 6, 41, 82, 123, 246

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,146,421,246, is 1.

Now, the common factors can be found like this.

661:661

146:2x 73

421:421

246:2x 3x 41

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 = 9994740396/(1x2)

LCM = 9994740396/2

LCM = 4997370198

Thus, we can understand that the LCM of 661,146,421,246 is 4997370198.
