Given numbers are 221,708,453,138

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

The LCM of 221,708,453,138 is 543413364.

Find LCM of 221,708,453,138 with Prime Factorization

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

2 x 3 x 221 x 118 x 151 x 23 = 543413364

Therefore, the lowest common multiple of 221,708,453,138 is 543413364.

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 708 x 453 x 138 = 9781440552

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

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

453 : 1, 3, 151, 453

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,708,453,138, is 1.

Now, the common factors can be found like this.

221:13x 17

708:2x 2x 3x 59

453:3x 151

138:2x 3x 23

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 9781440552/(1x18)

LCM = 9781440552/18

LCM = 543413364

Thus, we can understand that the LCM of 221,708,453,138 is 543413364.
