Given numbers are 221,249,370,854

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

The LCM of 221,249,370,854 is 8694031710.

Find LCM of 221,249,370,854 with Prime Factorization

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

2 x 221 x 249 x 185 x 427 = 8694031710

Therefore, the lowest common multiple of 221,249,370,854 is 8694031710.

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 249 x 370 x 854 = 17388063420

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

249 : 1, 3, 83, 249

370 : 1, 2, 5, 10, 37, 74, 185, 370

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,249,370,854, is 1.

Now, the common factors can be found like this.

221:13x 17

249:3x 83

370:2x 5x 37

854:2x 7x 61

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 = 17388063420/(1x2)

LCM = 17388063420/2

LCM = 8694031710

Thus, we can understand that the LCM of 221,249,370,854 is 8694031710.
