Given numbers are 247,156,357,293

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

The LCM of 247,156,357,293 is 103345788.

Find LCM of 247,156,357,293 with Prime Factorization

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

3 x 13 x 19 x 4 x 119 x 293 = 103345788

Therefore, the lowest common multiple of 247,156,357,293 is 103345788.

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.

247 x 156 x 357 x 293 = 4030485732

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.

247 : 1, 13, 19, 247

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

357 : 1, 3, 7, 17, 21, 51, 119, 357

293 : 1, 293

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,156,357,293, is 1.

Now, the common factors can be found like this.

247:13x 19

156:2x 2x 3x 13

357:3x 7x 17

293:293

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 4030485732/(1x39)

LCM = 4030485732/39

LCM = 103345788

Thus, we can understand that the LCM of 247,156,357,293 is 103345788.
