Given numbers are 217,478,272,155

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

The LCM of 217,478,272,155 is 70533680.

Find LCM of 217,478,272,155 with Prime Factorization

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

2 x 31 x 7 x 239 x 136 x 5 = 70533680

Therefore, the lowest common multiple of 217,478,272,155 is 70533680.

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.

217 x 478 x 272 x 155 = 4373088160

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.

217 : 1, 7, 31, 217

478 : 1, 2, 239, 478

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,478,272,155, is 1.

Now, the common factors can be found like this.

217:7x 31

478:2x 239

272:2x 2x 2x 2x 17

155:5x 31

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 4373088160/(1x62)

LCM = 4373088160/62

LCM = 70533680

Thus, we can understand that the LCM of 217,478,272,155 is 70533680.
