Given numbers are 742,274,386,198

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

The LCM of 742,274,386,198 is 1942302978.

Find LCM of 742,274,386,198 with Prime Factorization

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

2 x 371 x 137 x 193 x 99 = 1942302978

Therefore, the lowest common multiple of 742,274,386,198 is 1942302978.

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.

742 x 274 x 386 x 198 = 15538423824

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

274 : 1, 2, 137, 274

386 : 1, 2, 193, 386

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,274,386,198, is 2.

Now, the common factors can be found like this.

742:2x 7x 53

274:2x 137

386:2x 193

198:2x 3x 3x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 15538423824/(2x4)

LCM = 15538423824/8

LCM = 1942302978

Thus, we can understand that the LCM of 742,274,386,198 is 1942302978.
