Given numbers are 112,138,421,753

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

The LCM of 112,138,421,753 is 816625488.

Find LCM of 112,138,421,753 with Prime Factorization

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

2 x 3 x 56 x 23 x 421 x 251 = 816625488

Therefore, the lowest common multiple of 112,138,421,753 is 816625488.

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.

112 x 138 x 421 x 753 = 4899752928

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.

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

138 : 1, 2, 3, 6, 23, 46, 69, 138

421 : 1, 421

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 112,138,421,753, is 1.

Now, the common factors can be found like this.

112:2x 2x 2x 2x 7

138:2x 3x 23

421:421

753:3x 251

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 4899752928/(1x6)

LCM = 4899752928/6

LCM = 816625488

Thus, we can understand that the LCM of 112,138,421,753 is 816625488.
