Given numbers are 221,915,784,263,906

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

The LCM of 221,915,784,263,906 is 6295962407280.

Find LCM of 221,915,784,263,906 with Prime Factorization

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

2 x 3 x 221 x 305 x 392 x 263 x 151 = 6295962407280

Therefore, the lowest common multiple of 221,915,784,263,906 is 6295962407280.

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 915 x 784 x 263 x 906 = 37775774443680

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

915 : 1, 3, 5, 15, 61, 183, 305, 915

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

263 : 1, 263

906 : 1, 2, 3, 6, 151, 302, 453, 906

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,915,784,263,906, is 1.

Now, the common factors can be found like this.

221:13x 17

915:3x 5x 61

784:2x 2x 2x 2x 7x 7

263:263

906:2x 3x 151

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 37775774443680/(1x6)

LCM = 37775774443680/6

LCM = 6295962407280

Thus, we can understand that the LCM of 221,915,784,263,906 is 6295962407280.
