Given numbers are 347,178,242,420

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

The LCM of 347,178,242,420 is 1569474060.

Find LCM of 347,178,242,420 with Prime Factorization

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

2 x 347 x 89 x 121 x 210 = 1569474060

Therefore, the lowest common multiple of 347,178,242,420 is 1569474060.

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.

347 x 178 x 242 x 420 = 6277896240

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.

347 : 1, 347

178 : 1, 2, 89, 178

242 : 1, 2, 11, 22, 121, 242

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,178,242,420, is 1.

Now, the common factors can be found like this.

347:347

178:2x 89

242:2x 11x 11

420:2x 2x 3x 5x 7

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 = 6277896240/(1x4)

LCM = 6277896240/4

LCM = 1569474060

Thus, we can understand that the LCM of 347,178,242,420 is 1569474060.
