Given numbers are 221,219,416,515

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

The LCM of 221,219,416,515 is 797615520.

Find LCM of 221,219,416,515 with Prime Factorization

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

13 x 17 x 219 x 32 x 515 = 797615520

Therefore, the lowest common multiple of 221,219,416,515 is 797615520.

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.

221 x 219 x 416 x 515 = 10369001760

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.

221 : 1, 13, 17, 221

219 : 1, 3, 73, 219

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,219,416,515, is 1.

Now, the common factors can be found like this.

221:13x 17

219:3x 73

416:2x 2x 2x 2x 2x 13

515:5x 103

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

13 = 13

Therefore, the value for common factors is 13.

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 = 10369001760/(1x13)

LCM = 10369001760/13

LCM = 797615520

Thus, we can understand that the LCM of 221,219,416,515 is 797615520.
