Given numbers are 281,749,214,661

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

The LCM of 281,749,214,661 is 278240018.

Find LCM of 281,749,214,661 with Prime Factorization

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

107 x 281 x 7 x 2 x 661 = 278240018

Therefore, the lowest common multiple of 281,749,214,661 is 278240018.

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.

281 x 749 x 214 x 661 = 29771681926

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.

281 : 1, 281

749 : 1, 7, 107, 749

214 : 1, 2, 107, 214

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,749,214,661, is 1.

Now, the common factors can be found like this.

281:281

749:7x 107

214:2x 107

661:661

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

107 = 107

Therefore, the value for common factors is 107.

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 = 29771681926/(1x107)

LCM = 29771681926/107

LCM = 278240018

Thus, we can understand that the LCM of 281,749,214,661 is 278240018.
