Given numbers are 221,310,641,316

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

The LCM of 221,310,641,316 is 6938555780.

Find LCM of 221,310,641,316 with Prime Factorization

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

2 x 221 x 155 x 641 x 158 = 6938555780

Therefore, the lowest common multiple of 221,310,641,316 is 6938555780.

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 310 x 641 x 316 = 13877111560

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

310 : 1, 2, 5, 10, 31, 62, 155, 310

641 : 1, 641

316 : 1, 2, 4, 79, 158, 316

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,310,641,316, is 1.

Now, the common factors can be found like this.

221:13x 17

310:2x 5x 31

641:641

316:2x 2x 79

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

2 = 2

Therefore, the value for common factors is 2.

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 = 13877111560/(1x2)

LCM = 13877111560/2

LCM = 6938555780

Thus, we can understand that the LCM of 221,310,641,316 is 6938555780.
